boron carbide sand 1-3mm 3-5mm

boron carbide sand 1-3mm 3-5mm

Boron Carbide  is produced by high temperature smelting boric aid and carbon materails in electric furnaces.

Boron Carbide B4C powder has theoretic density of 2.52g/cm3;

Boron Carbide astm c750 B4C powder has melting point of 2450 C;

Boron Carbide astm c750 B4C’s microhardness is 4950 kgf/mm2

Boron Carbide astm c750 B4C’s hardness is just lower than diamond and cubic B4C.

Boron Carbide astm c750 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
