Boron carbide structural formula Boron carbide is a compound ， the chemical formula B4C, and its structural formula is as follows:B=C=B Boron carbide is composed of three covalent bonds between carbon and boron atoms. This is because the C and the B have three valence electrons. The covalent bond between C and B is non-bonded，giving

Boron carbide is a chemical raw material with high hardness/melting point, stable chemical properties, and neutron absorption characteristics. The following are the specific applications of boron carbide in chemical raw materials: Metal based friction material additives: Boron carbide is used as an additive in metal based friction materials to improve their hardness and wear resistance.
