As is known to all, purity is one of the main performance indexes of target materials. In practical application, the purity requirements of target materials are not the same. The application of high purity titanium target material compared with the general industrial pure titanium, high purity titanium is expensive, the application range is narrow. Mainly used to meet the needs of some special industries. So what are the main targets of high purity titanium? Now we follow baoji titanium alloy target material manufacturers to understand.

The application of high purity titanium target material mainly includes:

1. Biological materials

Titanium is a non-magnetic metal, will not be magnetized in a strong magnetic field, and has good compatibility with the human body, non-toxic side effects, can be used to manufacture human implants. General medical titanium materials do not reach the level of high purity titanium, but considering the dissolution of impurities in titanium, the purity of titanium used in implants should be as high as possible. It is also mentioned that high purity titanium wire can be used as biological strapping material. In addition, titanium injection needles with embedded catheters are of high purity titanium grade.

2, decorative materials

High purity titanium has excellent atmospheric corrosion resistance, long-term use in the atmosphere does not change color, to ensure the original color of titanium. Therefore, high purity titanium can also be used as building decoration material [5]. In addition, in recent years, some high-grade decorations and some wearables, such as bracelets, watches and spectacle frames, are made of titanium, which is resistant to corrosion, does not change color, can keep a good luster for a long time and contact with human skin is not sensitive and other characteristics. The purity of titanium used in some decorations has reached 5N.

3, inspiratory material

As a chemically active metal, titanium can react with many elements and compounds at high temperature. High purity titanium has a strong adsorption capacity for active gases (such as O2, N2, CO, CO2, water vapor above 650℃), and Ti film evaporating on the pump wall can form a surface with high adsorption capacity. This property makes Ti widely used as an getter in ultra-high vacuum gas extraction system. Such as used in sublimation pump, sputtering ion pump, can make the limit of the sputtering ion pump working pressure as low as 10-9PA.
