- Boron Carbide Designations:
Chemical Name: Boron carbide
- Boron Carbide Chemical Formula:
B4C
- Boron Carbide Powder Description:
a) A high performance abrasive material with chemical and physical properties similar to diamonds, such as chemical resistance and hardness. Boron carbide's extra hardness gives it the nickname "black diamond". Color is black or gray.
b) Boron carbide (chemical formula B4C) is an extremely hard ceramic material used in tank armor, bulletproof vests, and numerous industrial applications. With a hardness of 9.3 on the mohs scale, it is one of the hardest materials known, behind cubic boron nitride and diamond.
c) Boron carbide was discovered in the 19th century as a by-product of reactions involving metal borides, however, its chemical formula was unknown. It was not until the 1930s that the formula was determined to be B4C.[1] Boron carbide is now produced industrially by the carbo-thermal reduction of B2O3 (boron oxide) in an electric arc furnace.
