Boron carbide (chemical formula approximately B 4 C) is an extremely hard boron–carbon ceramic, a covalent material used in tank armor, bulletproof vests, engine sabotage powders, [2] as well as numerous industrial applications.
Boron carbide is a covalently bonded solid with a high melting point (2427°C), outstanding hardness (Vickers: 3770 kg/mm 2), good mechanical properties and low specific gravity (2.52 g/cm 2), making it ideal for use in lightweight armours. The nominal boron carbide stoichiometric formula is B 4 C; however, it has a very wide phase ...
