Chromium Carbide Cr₃C₂

Description

Chromium Carbide Cr₃C₂, an inorganic compound, gray powder with metallic luster, orthorhombic system structure, molecular weight 180.01, density 6.68g/cm³, melting point 1890°C, boiling point 3800°C, coefficient of thermal expansion 10.3×10^-6/K, is indissoluble in water and resistant to acid and alkali. Chromium Carbide is a kind of cermet material which has good wear resistance, corrosion resistance, anti-oxidation performance in high temperature environment and high microhardness. Chromium Carbide Cr₃C₂at Western Minmetals (SC) Corporation can be delivered in size of powder 0.5-500micron or 5-400mesh with package of 25kg, 50kg in plastic bag with iron drum outside.

Applications

Chromium Carbide Cr₃C₂ can be used as high temperature resistant, wear-resistant, oxidation resistant and acid resistant coating for aircraft engines and petrochemical mechanical components and devices to greatly improve the service life of machinery. Chromium Carbide Cr₃C₂ is commonly used as an additive of grain refiner to inhibit the growth of the alloy grains, and fine the crystalline grain in the production of cemented carbide and other wear-resistant and corrosion-resistant components. It is also expansively used to spray semiconductor film and as thermal spray material to protect the metal surface, or plasma spray in the metallurgy, electric power and petrochemical field.
