Tungsten Carbide Powder Introduction
1) Tungsten carbide is a made up of chemically bonded tungsten and carbide. Its superior hardness enables it to replace steel and other metal alloys in a variety of applications.
2) Colloquially, tungsten carbide is often simply called carbide. In its most basic form, it is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, tools, abrasives, as well as jewelry.
3) Tungsten carbide is approximately four times stiffer than steel, with a Young's modulus of approximately 550 GPa,and is much denser than steel or titanium. It is comparable with corundum (a-Al2O3) in hardness and can only be polished and finished with diamond wheels and compounds.

Tungsten carbide powder (WC) is the main raw material for producing cemented carbide, chemical formula WC. The full name is Wolfram Carbide, tungsten carbide powder is black six square crystal, has metallic luster, hardness is similar to diamond, it is 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 trioxide exists in the form of hydrate in nature, including mineral forms: wolfram (WO3? H2O), water tungsten oxide (WO3.2H2O) and water tungsten oxide. These minerals are rare and very rare secondary tungsten deposits.
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.
