Contact Supplierb4c is produced by high temperature smelting boric acid and carbon material in electric furnaces. It theoretic density is 2.52g/cm3, the melting point is 2450℃ ,and the microhardness is 4950kgf/mm2 .its hardness is just lower than diamond and cubic b4c. Because of high temperature resistance, acid and alkali resistance, high strength, good chemical stability , and low specific weight, it is widely used in many new materials fields.
