What’s boron carbide B4C? What are boron carbide’s uses?
Boron carbide B4C is produced by high-temperature smelting of boric acid and carbon materials in an electric furnace. Its theoretical density is 2.52 g/cm³, melting point is 2450℃, and microhardness is 4950 kgf/mm². Its hardness is second only to diamond and cubic boron nitride. It possesses characteristics such as high temperature resistance, acid and alkali corrosion resistance, high strength, high chemical stability, and low specific gravity, making it an ideal material for many industries.
