Tungsten carbide powder (WC) is the main raw material for the production of cemented carbide, chemical formula WC. Full name, tungsten carbide powder is black hexagonal crystal, has metallic luster, hardness is similar to diamond, and is a good conductor of electricity and heat. The melting point is 2870 ° C, the boiling point is 6000 ° C, and the relative density is 15.63 (18 ° C). Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, and easily soluble in a mixed acid of nitric acid and hydrofluoric acid. Pure tungsten carbide is brittle, and if a small amount of titanium, cobalt and other metals are added, brittleness can be reduced. Tungsten carbide used as a steel cutting tool is often added with titanium carbide, tantalum carbide or a mixture thereof to improve the explosion resistance. Tungsten carbide is chemically stable.
