Iridium

Discovery

Smithson Tennant

Smithson TennantIridium was discovered together with osmium in1803 by English chemist Smithson Tennant in London. When crude platinum was dissolved in dilute aqua regia (a mixture of nitric and hydrochloric acids), it left behind a black residue. Because of the black color, it was initially thought to be graphite. By treating it alternately with alkalis and acids, Tennant was able to separate it into two new elements. These he announced at the Royal Institution in London, naming one iridium (comeing from the Latin word ‘iris’, meaning rainbow) because many of its salts were so colorful; and the other osmium (derived from osme, the Greek word for smell) because it had a curious odor.

Specification

Name Iridium
Symbol Ir
Color silvery-white
CAS number 7439-88-5
Melting point 2446°C, 4435°F, 2719 K
Boiling point 4428°C, 8002°F, 4701 K
Density (g cm−3) 22.5622

Feature

Iridium is a rare, hard, lustrous, brittle, very dense platinum-like metal. Chemically it is almost as unreactive as gold. It is the most corrosion-resistant metal known and it resists attack by any acid. Iridium is generally credited with being the second densest element (after osmium) based on measured density, although calculations involving the space lattices of the elements show that iridium is denser.

Application

Due to its good corrosion-resistance, it is used of as a hardening agent for special alloy or to form an alloy with osmium, which is used for bearing compass and tipping pens.

Iridium Application

Iridium is used in making Iridium crucibles and other equipment that is used at high temperatures. Iridium sputtering target is a coating material to produce Iridium film, which is used as protective film or heavy-duty electrical contacts. In addition, Iridium was used in making the international standard kilogram, which is an alloy of 90% platinum and 10% iridium.

Planar Sputtering Target: Pros and Cons

Although the rotary targets have developed in recent years, the mainstream shape of the sputtering target is still the planar type. Today let us take a look at the pros and cons of planar targets to help you determine whether a planar sputtering target is suitable for your project.

Advantages of Planar Sputter Target

Simple structure – one of the main advantages of the planar target is that the structure is simple. The common planar targets on the market are rectangular planar targets and circular planar targets, which are easily produced by molds. In other words, planar target preparation requires fewer machines and technologies and is easier to prepare. This is why planar targets still dominate the sputtering target market.

Molds

Low price – You can never deny that the price is always an important competitive factor. As mentioned above, the manufacturing process of the planar sputter target is easier, so its price is much lower than the rotatory sputter target.

Strong versatility – Planar sputtering targets usually have strong versatility. Therefore, the transportation of the planar targets is relatively simple and is not easily damaged during transportation.

Good uniformity and repeatability – Film layers sputtered by planar targets usually boast good uniformity and repeatability. Planar targets are still best suited for prototype work or elemental experimentation, especially when large amounts of material are not needed at once.

Disadvantages of Planar Sputter Target

Its biggest disadvantage is the low utilization rate (generally only about 20%).  In the sputtering process of the planar target,  a strip-shaped pit will be formed when the target of the glow region (the magnetic field distribution region) is consumed to a certain extent, making the target body thinner. And once the pit depth reaches a certain value, the target cannot be utilized anymore. The low utilization rate also reduces its price advantage to some extent.

In conclusion, planar targets are still the best choice for prototype work or elemental experimentation, especially when large amounts of material are not needed at once. But its disadvantage of low utilization rate (20% vs. 80% compared with the rotatory target) does constrain its development.

Next week, let us look at the biggest competitor of the planar target– the rotatory target. Weighting the pros and cons of these two types of sputtering target may help you better choose the one for your application.

Who Discovered Yttrium? | Metal History

Yttrium is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a “rare-earth element“. Yttrium was discovered as early as the 18th century, but it has not been widely used until the last few decades in chemistry, physics, computer technology, film coating, medicine and other fields.

Yttrium History

In 1787, while the Swedish chemist Carl Axel Arrhenius exploring a quarry near Ytterby, a small town near Sweden’s capital city, Stockholm, he discovered an unusual black rock. He thought that he had discovered a new mineral, and sent some specimens to Johan Gadolin, a Finnish mineralogist, for analysis.

During the analysis, Gadolin isolated the yttrium from the mineral. The mineral was later named gadolinite in Gadolin’s honor, and Yttrium was named Ytterby from where the mineral was discovered.

In 1843, a Swedish chemist named Carl Gustaf Mosander studied yttrium samples and discovered three oxides, which were called yttria, erbia and terbia at that time. Currently, they are known as yttrium oxide (white), terbium oxide (yellow), and erbium oxide (rose-colored). A fourth oxide, ytterbium oxide, was identified in 1878.

Yttrium, a transition metal

In the Periodic Table of Elements, yttrium is considered one of the transition metals (yellow in the pic). Other more well-known transition metal elements include gold, silver and iron. The transition metals are the metallic elements that serve as a bridge, or transition, between the two sides of the table. They tend to be strong but pliable, therefore, some of these metals are widely used for wires. Yttrium wires and rods are used in electronics and solar energy. Yttrium is also used in lasers, ceramics, camera lenses, sputtering targets and dozens of other items.

A nebulizer for nodular cast iron.

A catalyst for ethylene polymerization.

Added in small quantities to reduce the grain size in chromium, molybdenum, etc., as well as to strengthen aluminum and magnesium alloys.

Yttrium sputtering target for film coating.

Yttrium compounds have the following uses:

Yttrium oxide is used to produce yttrium iron garnets.

Yttrium oxide is used in ceramic and glass formulations.

Yttrium oxide is widely used for making compounds such as YVO4europium and YVO4europium phosphors in television tubes.

Yttrium iron (Y3Fe5O12), yttrium aluminium (Y3Al5O12) and yttrium gadolinium garnets possess interesting magnetic properties.

Yttrium iron garnets are extremely efficient transmitters and transducers of acoustic energy.

Yttrium aluminum garnet has a hardness of 8.5 and is finding application as a gemstone.

Yttrium oxide sputtering target is used for film coating.

How was Chromium discovered? | Metal History

Chromium Discovery

In 1766, the German scientist Johann Gottlob Lehmann analyzed a Siberian ore and determined that it contained lead, which was classified as Siberian red lead.

Louis Nicolas Vauquelin
Louis Nicolas Vauquelin

 

In 1797, a bright red ore was found in the Siberian gold mine. The French chemist Louis Nicolas Vauquelin boiled the mineral with potassium carbonate, and got the lead carbonate and a yellow potassium salt solution of chromic acid. He added a high-mercury salt solution to the yellow solution, and a beautiful red solution appeared; the lead salt solution was added, and a yellowish precipitate appeared; when stannous chloride was added, the solution turned into a crisp green color. He thought that he had found a new metal, which was exactly chromium. The method produces metal chromium.

Chromium can produce beautiful multi-colored compounds: metallic chromium is silvery, chromium sulfate is green, magnesium chromate is yellow, potassium dichromate is orange, chromic is scarlet, and chromium oxide is green, chrome tanning is blue-violet, lead chromate is yellow…Thus Chromium got its name from the Greek word chroma, meaning color, and the chemical symbol is Cr.

Chromium Applications

Chromium was initially used as a pigment. At present, nearly all chromium is commercially extracted from chromite, also known as iron chromium oxide (FeCr2O4).

Chromium was considered to be a component of plants and animals in 1948. It was found to be biologically active in 1954. In 1957, chromium was identified as an essential trace element for animal nutrition. Chromium can act as an enhancer of insulin, affecting the metabolism of sugars, proteins, fats and nucleic acids through insulin.

As a metal element, chromium also has high industrial value. Chromium is widely used in metallurgy, chemical, cast iron, refractory and high-end technology industries.

Thinning and Coating Process of Mobile Phone Cover Glass

According to the needs of various terminal applications, glass cover panels require various optical glass processing processes such as cutting, edging, drilling, polishing, thinning, chemical strengthening, printing, laser engraving and coating. Today we will introduce the thinning and coating of mobile phone cover glass, which are the most important parts of the whole manufacturing process.

Cover glass thinning process

The glass mentioned in this article is not the 3mm, 5mm, 8mm or even 10mm glass for civil use, but the cover glass for electronic products such as smartphones and tablet computers. Among the glasses currently on the market, the thinnest is 0.15 mm. There is a special thinning process that reduces the thickness of the glass.

Since Steve Jobs started using Corning Gorilla Glass for his iPhones, there emerges a new component for electronic products—cover glass. At the same time, the pursuit of thinner and lighter in the industry is also urging glass manufacturers to make changes to make thinner cover glass.

iPhone cover glass
iPhone cover glass

Currently, the thinnest glass of gorilla can be made 0.4mm, and the Asahi Glass can make 0.2mm glass. In general, people’s expectations for cover glass are nothing more than two:

1. Reduce the space occupied by the glass.

2. Make the glass cover a certain flexibility.

Mobile phone cover glass thinning process

There are not many processes for glass cover thinning: pre-cleaning—etching and thinning—–secondary cleaning——-grinding (single or double sided)—–post-cleaning—–check the package

Pre-cleaning: Remove the stain on the surface of the glass cover. It is one of the key steps affecting the effect of thinning.

Etching and thinning:  using acid and alkali to etch the glass cover achieve the purpose of thinning. The conditions and parameters (time, potash ratio, temperature, etc.) vary from manufacturer to manufacturer, which is the technical secret of the manufacturer.

Secondary cleaning: Clean the residue of the glass cover.

Grinding: To obtain a bright, flat surface. It is one of the key processes for appearance assurance and thickness tolerance control.

Post-cleaning: Clean the remaining grinding powder.

Check the packaging: The standard for the appearance of the glass is different depending on the requirements of the customer.

Cover glass coating process

At present, vacuum magnetron sputtering coating technology is a widely used thin film deposition technology. The continuous development of sputtering technology and the exploration of new functional films have enabled the application of magnetron sputtering coating technology to be extended to many productions and scientific research fields.

magnetron sputtering coating applications

In the field of microelectronics, as a non-thermal coating technology, magnetron sputtering coating technology is mainly applied to materials that are not suitable for chemical vapor deposition or metal organic chemical vapor deposition. Moreover, using magnetron sputtering can obtain a large-area uniform film.

Magnetron sputtering technology is also used in optical films such as antireflection glass, low emissivity glass and transparent conductive glass. In the production of transparent conductive glass, the ITO conductive glass prepared by sputtering has an average transmittance of 90% or more in the visible light range.

In the modern machining industry, the use of magnetron sputtering technology to produce surface functional films, super hard films and self-lubricating films can effectively improve surface hardness, composite toughness, wear resistance and high temperature resistance and chemical stability, thus improve the service life of coated products.

In addition, magnetron sputtering coating technology also plays an important role in the research of high temperature superconducting thin films, ferroelectric thin films, giant magnetoresistive thin films, thin film luminescent materials, solar cells, and memory alloy thin films.

Magnetron sputtering coating advantages

Magnetron sputtering coating technology has become one of the main technologies of the industrial coating due to its remarkable advantages:

(1) Simple operation and easy control. In the coating process, if the sputtering conditions such as working pressure and electric power are relatively stable, the deposition rate is relatively stable.

(2) The deposition rate is high. When depositing most of the metal, especially the high melting point metal and oxide, such as tungsten, aluminum TiO2 and ZrO2 film, it has a high deposition rate.

(3) Low temperature of the substrate. Compared to two-pole sputtering or thermal evaporation, magnetron sputtering reduces the heating of the substrate, which is quite advantageous for achieving the sputter coating of the fabric.

(4) The sputtered film is strong. The sputtered film has excellent adhesion to the substrate and its mechanical strength is also improved.

(5) The sputtered film is dense and uniform. From the photomicrograph, the surface morphology of the sputtered film is fine and uniform.

(6)The sputtered films all have excellent properties. For example, sputtered metal films generally achieve good optical properties, electrical properties, and certain special properties.

(7) Easy to mass produce. The magnetron source can be expanded as required, so large-area coatings are achievable. In addition, sputtering can work continuously, and the coating process is easy to control automatically, so that the industrial assembly line can be realized.

(8) Environmentally friendly. Conventional wet plating produces waste liquid, waste residue, and exhaust gas, causing serious pollution to the environment. The magnetron sputtering coating method has high production efficiency while does not cause environmental pollution.

How to make the phone case of gradient color like Huawei P20?

Gradient color is popular in 2018

It’s overwhelming how many smartphone models are currently available on the market today.  However, as for the color of the phone, what get are the same old black, white, silver and gray, in glossy or matte.

Well, recently an exciting new trend has emerged. The Huawei P20 series let people see the optimal color design and professional photography. A few months ago, Huawei launched the P20 in Twilight, and the dual-tone gradient inspired by the Aurora Borealis made people feel excited.

Well, these are just a few examples to show that gradient color is the fashion of the year 2018. Are you curious about how to achieve this kind of gradient color? Is it difficult?

Film coating-Physical vapor deposition

Actually, all the color of the shell is about film coating. A cellphone is made from a variety of metals, with the most common being aluminum alloys, lightweight materials commonly found in the phone case. And the film coating is to apply a colored film on the phone case.

Physical vapor deposition is the most widely used film coating technology. Under vacuum conditions, the surface of the material (usually referred to as the sputtering targets or evaporating pellets) is vaporized into gaseous atoms by physical methods, and is then deposited on the surface of the substrate to form a thin film. The main methods of physical vapor deposition include vacuum evaporation, sputtering coating, plasma coating, ion plating, and molecular beam epitaxy.

How to coat the gradient color

PVD can coat gold, brass, rose gold, silver white, black, smoky, copper, brown, purple, blue, burgundy, bronze and other colors on stainless steel, copper, zinc alloy and other metals. There are many choices and the price is affordable, compared to pure gold or other pure metals. (PVD Coating Materials.pdf) You can refer to our previous article for more information: Introduction to PVD Coatings.

By controlling the parameters of different targets and thickness of the deposited film, the film exhibits different colors (the gradation colors mentioned above) under the reflection, refraction and interference of light. Specifically, in the plating furnace space, bombard a specific sputtering target with ultra-high speed electrons; use a certain mask to cover a part of the ion cloud so that only the other part of the ion cloud can be attached to the substrate and forms a very thin layer of nano-plating; control the thickness of the coating to form a nanometer thickness difference; then spray the background color.

How was Silicon discovered? | History of Silicon

Silicon

Discovery of Silicon

In 1787, the French chemist Antoine-Laurent de Lavoisier first discovered the silicon present in rocks. In 1800, silicon was mistaken by Sir Humphry Davy as a compound. In 1811, French chemists Joseph Louis Gay-Lussac and Louis Jacques Thénard probably prepared impure amorphous Silicon by heating potassium with silicon tetrafluoride. They later named it silicon according to the Latin silex (meteorite).

Until 1823, silicon was first discovered in the form of a metal element by the Swedish chemist Jöns Jacob Berzelius. One year later, he extracted amorphous silicon in much the same way as Gay-Lussac, and then purified the elemental silicon by repeated cleaning; in the same year, he heated the silicon oxide powder and the mixture of iron and carbon at a high temperature and obtain the iron silicide.

In order to extract pure silicon, Berzelius dry-fired the silicon-fluorine-calcium compound, hydrolyzed the obtained solid, and manage to obtain the pure silicon. In 1824, in Stockholm, Berzelius obtained relatively pure silicon powder by heating potassium fluorosilicate and potassium. Therefore, it is agreed that the honor of discovering silicon belongs to Berzelius.

Properties of Silicon

Symbol: Si
Atomic Number: 14
Atomic Weight: 28.09
Element Category: metalloid
Color: dark gray with a bluish tinge
Density: 2328.3 kg/m³
Hardness: 6.5
Proportion in Earth’s Crust: 25.7%
Other Names: Silicium, Silicio

Application of Silicon

High-purity monocrystalline silicon is an important semiconductor material that can be used as a solar cell to convert radiant energy into electrical energy, which is a promising material in the development of energy.

Silicon can also be made into cermet composites, which are resistant to high temperatures, toughness, and can be cut. They not only inherit the respective advantages of metals and ceramics, but also make up for the inherent defects of both, and can be applied to weapons manufacturing and aerospace.

Pure silica can be used to draw high transparency glass fiber for optical fiber communication, which is the latest modern communication means.

What is the Indium Bonding for Sputtering Target?

The term “indium bonding” in thin film coating industry, simply speaking, refers to bond two (or more) sputtering targets with indium (In), or one (or more) with indium plate together.

Indium

Indium can be uniquely used in lower temperature solders, is one of the softest materials. Indium is preferred for target bonding because of its excellent thermal conductivity of all available bonds. In addition, indium is the most efficient material at drawing heat away from the sputtering target. Most materials can be indium bonded and there are just a few exceptions.

Apart from indium bonding, indium is also popular for a variety of uses and purposes, such as creating alloys, photoconductors, and thermistors.

Indium bond

Sputtering target can be cracked, warped or damaged due to inadequate cooling, low hardness or other reasons. From this point of view, although target bonding does generate a fee, it can well protect your target from damage. It is especially true for those less-strong target materials and precious metal materials.

Elastomer is an alternative bonding method that touts a higher temperature capability over the indium bond. Elastomer bonds are recommended when you are consistently melting indium bonds. We also recommend elastomer bonding for low melting point target materials, as well as, temperature sensitive compounds and targets that have either low density or are especially fragile.

indium target bonding

Indium bonding is preferred in applications where:

Cryogenic stability is needed

Sealing requires high levels of hermeticity

Maximum thermal transfer is required

Bonding to not-metallic surfaces

Flux cannot be used

Backing plates

OFHC Copper Backing Plate is another well-known backing plate. It is frequently used to bond ceramic targets because of its non-magnetism and low coefficient of thermal expansion. This metal has good electrical and thermal characteristics while also being easy to machine, easy to soften, and readily available at a low cost. Copper backing plates can be re-used, with care, 20 or more times.

Molybdenum plate is usually used to substitute copper plate if copper is not appropriate in the application. For instance, the coefficient of expansion for copper is mismatched with some ceramics. And for high-temperature bonding, copper may also oxidize badly or warp. In these conditions, molybdenum is a more suitable material.

SAM Sputter Target

If you are looking for an indium bonding manufacturer, SAM is undoubtedly your best choice. Stanford Advanced Materials is devoted to machining standard backing plates and working together with the Taiwan Bonding Company for providing bonding services. For questions about target bonding materials, methods and services, please see our listing of frequently asked questions (FAQs).

Molybdenum Target Mammography Detection

Breast cancer, one of the major causes of deaths among women, affects about 12% of women around the world. According to research surveys, the smaller the breast cancer is when it is detected, the less the possibility of death. This requires that women should go over the medical body check regularly to decrease the risk of breast cancer. At present, molybdenum target mammography is considered the recommended breast screening examinations for women’s breast cancer.

What is the Breast Cancer?

Breast cancer is caused by the development of malignant cells in the breast. It is a sign of breast cancer when cells in the breast begin to grow out of control, and these cells usually result in forming a tumor.

Breast Cancer
Breast Cancer

 

Breast cancer itself is not a fatal disease because the breast is not an indispensable organ for maintaining human life. However, if the malignant cells spread to other important parts of the human body, such as the heart, the liver, and kidney, breast cancer may lead to death.

Breast cancer occurs almost entirely in women, but men can get breast cancer, too. And it is closely related to age—only 5% of all breast cancers occurring in women under 40 years old.

What is Molybdenum target mammography?

Molybdenum target, or molybdenum sputtering target, is known as the materials in physical vapor deposition for film coating.

Molybdenum target mammography is another important application of Molybdenum target. It is a non-invasive method to test breast diseases such as breast mass and calcification. From the viewpoint of techniques, it is a digital imaging technology that combines traditional radiology technology with modern computer technology that transforms the X-ray image into a digital image that can be quantized. Molybdenum target mammography enables radiologists to find suspicious malignant lesions in mammography easier. Thus, it has been used as a routine examination to reduce the risk of breast cancer.

Molybdenum Target Mammography

Why is Molybdenum target mammography beneficial?

Molybdenum target mammography is currently the primary choice for the diagnosis of breast disease. It is an easy and non-invasive method of examination which can accurately reflect the condition of the entire breast. What’s more, it can be used to observe the breast disease caused by various factors and the results are relatively reliable. With the help of Molybdenum inspection, some precancerous lesions can be found and can be followed up for observation. So it is beneficial for women’s health.

Above information is from SAM Sputter Target, a global sputtering targets manufacturer specialized in Molybdenum target.
