Tungsten Oxide

Tungsten carbide is a chemical compound containing equal parts of tungsten and carbon atoms. In the tungsten carbide powder, carbon atoms will embed in the interstice of tungsten metal lattice, which will not destroy the lattice of original metal and will form interstitial solid solution. Therefore, it can be also called interstitial compound or insertion compound, which is mainly used in producing cemented carbide due to its high hardness. As tungsten carbide powder has large application range, it has given rise to the waves of researching the preparation of tungsten carbide powder. Violet tungsten oxide can be used in producing tungsten carbide powder, this is because it has single-crystal structure, abundant crack as well as its interior is composed by loose needle-like or rod like particles, which will be beneficial for making tungsten carbide powder that has superior quality.
