Cr3C2=180.02, with 13.34% C, is grey powder with bias crystalline structure and acid resistance and does not dissolve in water.Density:6.65-6.68g/cm3,melting point:1890℃,boiling point:3800℃.It is a high-point melting inorganic material with good wear resistance, acid resistance and oxide resistance in high-temperature circumstance and used in thermal spray material on metal cover, cemented carbide and other wear-resistance, corrosive-resistance parts. The metal ceramic in basis of Cr3C2 has excellent oxide resistance and the surface just become a little dark after exposing under 982℃ 5 hours later, but in same condition,188 stainless steel is heavily destroyed and WC6CO is completed oxidised.
