The resistance of solid phase sintering between pure tungsten carbide powders is very high. It is difficult to obtain high density materials with densities of more than 99% without binder. At present, the research on pure tungsten carbide targets contains binder phases, such as TiC, TaC and Co.

In individual protection, the armor materials used for bullet-proof include alumina, silicon carbide, boron carbide, silicon nitride, titanium diboride and so on. At present, conventional weapons are developing rapidly, and the threat level to individual soldiers is gradually increasing. In order to improve the survivability and mobility of individual soldiers, it is necessary to develop a lightweight and efficient ballistic composite system.

With the development of coating technology, coating on device surface has become an effective method of wear resistance and corrosion protection. In recent years, tungsten carbide thin film coating technology has been widely studied for the protection of steel and other metal materials. With the functionalization of devices and the increasingly complex shape, modern industry has put forward higher requirements for protective coatings applied on its surface.

Nano-tungsten carbide powder is an important raw material for superfine cemented carbide. At the same time, nano-tungsten carbide powder has high specific surface area, which is also conducive to improving its catalytic performance and advantages as catalyst carrier. Therefore, the study of nano-tungsten carbide is of great significance.
