Product Description

Product Description

 

Tungsten carbide powder

Tungsten carbide powder (WC) is the main raw material for producing hard alloys, with the chemical formula WC. The full name is tungsten carbide powder, which is a black hexagonal crystal with metallic luster and hardness similar to diamond. It is a good conductor of electricity and heat. Melting point 2870 ºC, boiling point 6000 ºC, relative density 15.63 (18 ºC). Tungsten carbide is insoluble in water, hydrochloric acid, and sulfuric acid, but is easily soluble in a mixed acid of  and . Pure tungsten carbide is fragile, and adding a small amount of titanium, cobalt, and other metals can reduce brittleness. Tungsten carbide, which is used as a steel cutting tool, is often added with Titanium carbide, Tantalum carbide or their mixture to improve the antiknock ability. The chemical properties of tungsten carbide are stable.
Nature
Tungsten carbide powder is a dark gray powder, which can be dissolved in a variety of carbides, especially in Titanium carbide, with a high solubility, forming TiC-WC solid melt. Another compound of tungsten and carbon is tungsten carbide, with the chemical formula W2C, a melting point of 2860 ºC, a boiling point of 6000 ºC, and a relative density of 17.15. Its properties, preparation method, and use are the same as tungsten carbide powder.
Purpose
Tungsten carbide powder
Tungsten carbide powder is mainly used for the production of hard alloys. In tungsten carbide powder, carbon atoms embedded in the gaps of tungsten metal lattice do not destroy the original metal lattice, forming interstitial Solid solution, so it is also called interstitial (or inserted) compound.
