Boron Carbide is with a Mohs hardness between 9 and 10, one of the hardest synthetic substances known, being exceeded only by cubic boron nitride and diamond. As an abrasive, it is used in powdered form in the lapping (fine abrading) of metal and ceramic products. Because of its hardness, together with its very low density, it has found application as a reinforcing agent for armors. Its wear resistance has caused it to be applied in sandblasting nozzles and pump seals. As neutron absorber, boron carbide is used in powdered or solidified form to control the rate of fission in nuclear reactors.
