Solubility in water: insoluble
Crystal structure: rhombohedral
Main hazard: harmful, irritant
Relative molecular weight: 55.26
Storage: sealed.
Purpose: Chemical resistant pottery, wear-resistant tool manufacturing.

Hard black shiny crystal. The hardness is lower than industrial diamond, but higher than silicon carbide. Compared with most pottery, it is less fragile. It has a large thermal neutron capture cross section. Strong chemical resistance. It is not subject to the erosion of hot hydrogen fluoride and nitric acid. Soluble in molten alkali, insoluble in water and acid. Relative density (d204) 2.508 ~ 2.512. The melting point is 2350 ℃. The boiling point is 3500 ℃.

Boron carbide, also known as black diamond, is an inorganic substance with the chemical formula of B ₄ C and is usually gray black powder. It is one of the three hardest materials known (second only to diamond and cubic boron nitride) and is used in tank armor, bullet-proof clothing and many industrial applications. Its Mohs hardness is about 9.5.

Boron carbide can absorb a large number of neutrons without forming any radioisotopes, so it is an ideal neutron absorber in nuclear power plants, and the neutron absorber is mainly used to control the rate of nuclear fission. Boron carbide is mainly made into controllable rods in the nuclear reactor field, but sometimes it will be made into powder due to the need to increase the surface area.

Because of its low density, high strength, high temperature stability and good chemical stability. It is used in wear-resistant materials, ceramic reinforcement, especially in light armor, reactor neutron absorber, etc. In addition, compared with diamond and cubic boron nitride, boron carbide is easier to manufacture and cheaper to use, so it can be used more widely. In some places, it can replace the expensive diamond and is commonly used in grinding, grinding, drilling, etc.

It is characterized by low density, high strength, high temperature stability and good chemical stability. In wear resistant materials, ceramic   reinforcement, especially in light armor, reactor neutron absorbent applications. In addition, compared with diamond and cubic boron nitride, boron   carbide is easy to manufacture, low cost, so it is more widely used, in some places can replace the expensive diamond, common in grinding,   grinding, drilling and other applications
