Tungsten carbide is a compound consisting of tungsten and carbon. It is a black six crystal. It has a metallic luster. The hardness is similar to that of diamond.
The production process of tungsten carbide is not complicated, the tungsten powder and carbon black were mixed into the ball mill, carbonization of graphite tube resistance or corundum tube molybdenum wire furnace under the condition of hydrogen as protective atmosphere.
The hardness of tungsten carbide is high, Mohs hardness is 8.5 ~ 9, second only to diamond. The melting point of tungsten carbide is also very high, reaching 2870 degrees C Celsius or 5198 degrees F fahrenheit.
Tungsten carbide is widely used as cutting tool material for mechanical industry, high hardness armor or armor piercing bullet core for military industry because of its high hardness and heat resistance. Tungsten carbide has high wear resistance and corrosion resistance, so it is also used to make wearable thermal protection coatings for wear tools in aerospace industry and precision industry.
Nano tungsten carbide also has stable physical and chemical properties, and has the catalytic properties similar to noble metal platinum. Therefore, it is a catalyst for platinum replacement in new energy batteries.
Tungsten carbide can form solid solution with many carbides. WC-TiC-Co cemented carbide cutting tools have been widely used. It can also be used as modifying additive of NbC-C and TaC-C three element system carbide. It can not only reduce sintering temperature, but also maintain good properties, and can be used as aerospace materials.
