Boron carbide is one of the hardest man-made materials, highly abrasive and used as an abrasive to process gemstones.Ceramics. Cutters. Bearings.Hard alloys. Grinding, grinding, drilling and polishing of precision components.

The hardness is 9.36, the microhardness is 5400 6,300 kg/m2, the density is 2.52 kg/m2, the melting point is 2450 Degrees Celsius. Boron carbide is a hexahedron crystal system dark black color, and boron carbide is mainly used as an additive in refractory materials.Wear - resistant welding rods. Etc.High temperature resistance. Wear - resistant products densified boron carbide made of sand - blasting nozzle.Mechanical seals. Bulletproof materials, due to boron carbide has a large thermal neutron capture cross section.It absorbs a lot of neutrons.Can be used in nuclear reactor and other high-tech fields.
