Chromium carbide is an inorganic compound with a chemical formula of Cr3C2 and a molecular weight of 180.01. Chromium carbide (Cr3C2) is gray powder with metallic luster. Chromium carbide powder has good wear resistance, corrosion resistance and oxidation resistance under high temperature environment (1000-1100℃).

Chromium Carbide Preparation

Metal chromium powder carbonization method:
The carbon black is pulverized with electrolytic chromium at a ratio of 13.5% to 64% (more than the theoretical combined carbon amount of 11.33% by mass) to form 325 mesh metal chromium powder, which is dry mixed with a ball mill as a raw material.

Add 1% to 3% stearic acid as a lubricant for molding, press molding with a pressure of 1 T/cm2 or more, put the pressed molding powder into a graphite pan or crucible, and use a Taman furnace or an induction heating furnace. In a hydrogen stream (hydrogen dew point is around -35°C), heat to 1500-1700°C and keep it for 1h to make chromium undergo carbonization reaction to produce chromium carbide. After cooling, chromium carbide is produced.

 
 

Chromium Carbide Application

1. Chromium carbide is a high melting point material with good wear resistance, corrosion resistance and oxidation resistance in high temperature environments. It is made of nickel-chromium alloy with cemented carbide particles. Plasma spraying can be used as a high temperature resistant, Wear-resistant, oxidation-resistant and acid-resistant coatings are widely used in aircraft engines and petrochemical machinery components, which can greatly increase the life of the machinery.

2. Chromium carbide is also often used as a grain refiner for cemented carbide and other wear-resistant and corrosion-resistant components. Cermets based on Cr3C2 have excellent oxidation resistance at high temperatures.

3. Chromium carbide is used for chromium carbide ceramics. Coarse-grained chromium carbide is used as a melt-blown material to form a melt-blown coating on the surface of metals and ceramics, giving the latter properties such as wear resistance, heat resistance, and corrosion resistance. It is widely used in aircraft engines and petrochemical machinery components to greatly improve the machinery life.

4. Chromium carbide is also used to spray semiconductor film.
