Properties of Boron carbide CAS 12069-32-8
Boron carbide is a black crystal with metallic luster. Its hardness is second only to diamond and higher than silicon carbide, with a Mohs hardness of 9.3. It is chemically stable and does not react with acid and alkali solutions. The molecular formula is B4C, the relative density is 2.52Chemicalbook, the melting point is 2350℃, and the boiling point is higher than 3500℃. The molten boron carbide can dissolve a large amount of graphitic carbon. Boron carbide is stable in dilute acid solution and can be decomposed by the mixed acid of sulfuric acid and hydrofluoric acid, and the mixed acid of sulfuric acid and nitric acid.
