chromium carbide properties

density:6.65-6.68g/cm3
melting point:1890℃
boiling point:3800℃.
molecular weight:80.02

Chromium carbide powder, with 13.34% Carbon, is a grey powder with bias crystalline structure and acid resistance and does not dissolve in water. It is a high-point melting inorganic material with good wear resistance, acid resistance and oxide resistance in high-temperature circumstances and is used in thermal spray material on the metal cover, cemented carbide and other wear-resistance, corrosive-resistance parts. The metal-ceramic in the basis of Cr3C2 has excellent oxide resistance and the surface just becomes a little dark after exposing under 982℃ 5 hours later, but in the same condition,188 stainless steel is heavily destroyed and WC6CO is completed oxidized.
