Application of titanium and titanium alloys in medical field

Titanium is an ideal medical metal material and can be used as an implant for human body. Titanium alloy has been widely used in the medical field and has become the material of choice for medical products such as artificial joints, bone trauma, spinal orthopedic internal fixation systems, dental implants, artificial heart valves, interventional cardiovascular stents, and surgical instruments.

Application of titanium alloy in facial treatment

When the human face is severely damaged, local tissue repair should be treated by surgical implantation. Titanium alloy has good biocompatibility and required strength, so it is an ideal material for facial tissue repair. The skull bracket made of pure titanium mesh has been widely used in the reconstruction of the humerus and has achieved good clinical results.

Application of titanium in the pharmaceutical industry

SAM®Titanium is mainly used in the pharmaceutical industry for making containers, reactors, and heaters. Equipment used in the production of pharmaceuticals is often exposed to inorganic acids, organic acids, and salts, such as hydrochloric acid, nitric acid, and sulfuric acid. Therefore, these devices are easily damaged by long-term corrosion. On the other hand, steel equipment will introduce iron ions that affect product quality.

These problems can be solved with titanium equipment. For example, a penicillin esterification kettle, a saccharification tank, a chloramphenicol thin film evaporator, a dimethyl sulfate cooler, a chemical liquid filter, all have precedents for selecting a titanium material.

Application of titanium in medical devices

In the history of the development of surgical instruments, the first generation of surgical instruments was mostly made of carbon steel, which was eliminated because the performance of carbon steel instruments after electroplating did not meet the clinical requirements. The second generation is austenitic, ferritic and martensitic stainless steel surgical instruments. However, due to the toxicity of chromium in the stainless steel composition, the chrome-plated layer has a certain influence on the human body. Therefore, the third generation–titanium surgical instrument appeared.

The lightweight and high strength of titanium make it particularly suitable for microsurgery. Titanium has the advantages of corrosion resistance, good elasticity, and no deformation; even after repeated cleaning and disinfection, the surface quality of titanium is not affected; titanium is non-magnetic and does not pose a threat to tiny, sensitive implanted electronic devices. These advantages make the application of titanium surgical instruments more and more extensive. At present, titanium has been used to make surgical blades, hemostats, scissors, electric drills, tweezers and so on.

Application of titanium and titanium alloys in dentistry

Metals used in dental surgery began with amalgams and metal crowns in the 1920s. In the 1960s, gold, silver, and palladium alloys were mainly used. After the 1970s, stainless steel became the most commonly used material for permanent and detachable instruments for orthodontics. In the 1990s, titanium casting technology was promoted and applied.

Purity

Purity is one of the main performance indicators of sputtering targets because it has a great influence on the performance of the film. Taking titanium target as an example, the higher the purity is, the better the corrosion resistance and electrical and optical properties of the sputtered film are. However, in practical applications, the purity requirements of the sputtering targets are not the same. Generally, the purity requirements of industrial targets are not high, but the sputter targets for semiconductors, display devices have very strict requirements–the purity requirements of magnetic film targets are generally 99.9% or more, and the purity of indium oxide and tin oxide in ITO targets is required to be not less than 99.99%.
