Tungsten carbide powder (WC) is the main raw material for producing cemented carbide, chemical formula WC. The full name is Wolfram Carbide, also translated as tungsten carbide for black six square crystals, with metallic luster, hardness similar to diamond, and a good conductor of electricity and heat.
Tungsten oxide is a tungstic anhydride and a tungstate product. Tungsten oxide is an oxide of tungsten. It is an important intermediate for the preparation of tungsten from tungsten ore. Tungsten oxide can be used to produce chemical products, such as paint and coatings, petroleum industry catalysts, etc.
Tungsten is a parent stone element, which mainly exists in the pegmatite and hydrothermal deposits in the form of tungstate; there are about 15 known tungsten ores, of which there are mainly two wolframite and scheelite.
