Boron carbide is one of the hardest man-made materials, with high grinding efficiency. It is used as an abrasive for grinding, lapping, drilling, and polishing of gemstones, ceramics, cutting tools, bearings, cemented carbides, and precision components.

It does not react with strong acids or strong bases. Its Mohs hardness is 9.36, microhardness ranges from 5400 to 6300 kg per square meter, density is 2.52 kg per square meter, and melting point is 2450 degrees Celsius. Boron carbide has a hexagonal crystal system and is dark black in color. It is primarily used as an additive in refractory materials, wear-resistant welding rods, and other high-end products requiring oxidation resistance, high-temperature resistance, and wear resistance. Dense boron carbide is used to manufacture sandblasting nozzles, mechanical seals, and bulletproof materials. Due to its large thermal neutron capture cross-section, boron carbide can absorb a large number of neutrons and is used in high-tech fields such as nuclear reactors.
