What material does hexagonal boron carbide grind?

Boron carbide, also known as boron tetraborate, is a kind of gray-black powder and a kind of boride with high hardness, so it is often called synthetic diamond, which is relatively easy to prepare and has low production cost. It is widely used in manufacturing superhard tools or grinding and drilling hard materials. Boron carbide is one of the hardest man-made materials with high grinding efficiency. As an abrasive, it can be used for grinding, grinding, drilling and polishing gems, ceramics, tools, bearings, cemented carbide and precision parts.

It cannot react with strong acid and alkali, with Mohs hardness of 9.36, microhardness of 5400-6300 kg/m2, density of 2.52 kg/m2 and melting point of 2450 degrees Celsius. Boron carbide is hexagonal dark black, and boron carbide is mainly used as an additive in refractories. Wear-resistant covered electrode and other advanced anti-oxidation, high-temperature and wear-resistant products. Densified boron carbide is made into sandblasting nozzle, mechanical seal and bulletproof material. Because boron carbide has a large thermal neutron capture cross section, it can absorb a large number of neutrons and can be used in high-tech fields such as nuclear reactors.
