The main characteristics of nano-chromium carbide ultrafine chromium carbide powder prepared through a special process, the powder is orthorhombic, a = 2.821, b = 5.52, c = 11.46, relative density 6.68, melting point 1890 ° C, boiling point 3800 ° C, thermal expansion coefficient of 10.3 x 10-6 / K; chromium (chromium oxide) and carbon compounds from the high temperatures of 1400-1600 ℃, chromium carbide lattice of positive and negative, density is 6.613 g/cm3, a melting point of 1895 ℃. chromium carbide is gray to acid.
Applications
An anti-wear films, semiconductor films;
Carbide production to add the Cr3C2 not only able to refine the WC grain size and improve tensile strength and hardness and can significantly improve the alloy’s corrosion resistance in industrial production is widely used as corrosion-resistant alloy structural materials (gauge valve, sealing rings, etc.) used for spray welding and surfacing requirements of both corrosion resistance and the hard surface of the high resistance to friction performance solder; widely used in stainless steel, heat resistant steel, corrosion-resistant steel, alloy steel and special steel smelting production
