1) Application of boron carbide structure as material In the industrial application field of boron carbide materials, boron carbide is first used as an abrasive, from powder with a particle size of 1um to pellets with a diameter of 10mm. For example, boron carbide is used as an abrasive for other hard materials such as

Study on the effect of boron carbide on the performance of silicon-based ceramic cores The specific effect of boron carbide on the properties of silicon-based ceramic cores Shrinkage rate and bulk density: With the increase of boron carbide content, the shrinkage rate and bulk density of silicon-based ceramic cores gradually increase. This may be due

Chemical stability of boron carbide Boron carbide is one of the most stable compounds and is not prone to oxidation reactions below 600°C; when the temperature is higher than 600°C, a B2O3 film is formed due to surface oxidation, preventing further oxidation of B4C. Antioxidants. The film has significant micropore size (HV=24GPa) and fatigue resistance.
