About chromium carbide CR3C2 powder
The chromium carbide powder is a very hard refractory ceramic material. It is a fine gray powder, rarely natural mineral Tongbai. Carbonized chromium carbide has strong corrosion resistance and high temperature oxidation properties, and its thermal performance is similar to steel. It is an excellent material for many commercial industries. Several different carbicide compounds can be formed, and the mechanical properties and applications of each compound are slightly different. Chromium carbide is used as a thermal spray material that protects the underlying metal surface and is used as an additive for corrosion resistance and abrasion resistance. In places where there is a sliding wear, the application of chromium carbide is particularly effective. If you want to purchase a batch of chromium carbide CR3C2 powder in batches, please feel free to send an inquiry to get the latest price.
How to produce chromium carbide CR3C2 powder?
Chromium carbide was produced by combination of aluminum heat reduction and vacuum furnace at a temperature of 1500 ° C. A mixture of chrome metal, chromium oxide and carbon is prepared, and then load it into a vacuum furnace. Reduce the pressure in the furnace and increase the temperature to 1500 ° C. Carbon and chromium oxide reactively form chrome metal and carbon monoxide gas to discharge it into a vacuum pump. The chromium metal is then carbicide with the remaining carbon.
The precise balance between chromium oxide, chromium metal and carbon determines the grade of the produced chromium carbide. Strictly control this to ensure product quality is suitable for markets such as aerospace.

Chromium carbide CR3C2 powder properties
Carbonized chromium carbide, containing 13.34% carbon, is a gray powder, a plasma crystal structure, insoluble in water, acid resistance and alkali. The density is 6.65-6.68 g / cm3, melting point: 1890 degrees, boiling point: 3800 degrees. It is a high melting point inorganic material, which has good wear resistance, corrosion resistance and oxidation resistance in a high temperature environment (1000-1100 degrees). It is used as a thermal spray material protected by metal surface, and is often used as a hard alloy. Cereal grinding machine and other wear resistant components. The chromium carbide has excellent oxidation resistance at high temperatures, and the surface is only slightly black after 5 hours in 982 ° C exposure. In the same conditions, 18-8 stainless steel has been severely damaged.
