325mesh 200mesh 100 mesh 95% B4C grade boron carbide in ceramic industry
Boron Carbide powder B4C is produced by high temperature smelting boric aid and carbon materails in electric furnaces.
Boron Carbide powder B4C has theoretic density of 2.52g/cm3;
Boron Carbide powder B4C has melting point of 2450 C;
Boron Carbide B4C’s microhardness is 4950 kgf/mm2
Boron Carbide B4C’s hardness is just lower than diamond and cubic B4C.
Boron Carbide B4C powder have high temperature resistance,acid and alkali resistance,high strengh,good chemical stability,and low specific weight,so Boron Carbide B4C powder is widely used in many new materials fields
