Boron Carbide B4C
Product Description
Hard, black, shiny crystals. Hardness is lower than industrial diamond, but higher than silicon carbide. Fragility is lower than most pottery. Has a large thermal energy neutron capture cross section. Strong chemical resistance. Not subject to the attack of hot hydrogen fluoride and nitric acid. Soluble in molten alkali, insoluble in water and acid.
Common Sizes:60-150 80-120mesh
boron carbide B4C is produced by high temperature smelting boric aid and carbon materails in electric furnaces.
