Boron carbide, also known as black diamond, is an inorganic substance with a chemical formula of B4C, usually a gray-black micropowder. It is one of the three hardest known materials (after diamond and cubic boron nitride) and is used in tank armor, body armor and many industrial applications. It has a Mohs hardness of about 9.5. Black glossy crystals. The hardness is lower than that of industrial diamond, but higher than that of silicon carbide.

Application of Nano-Boron Carbide (Supply 100-200nm)

1. Control nuclear fission
Boron carbide (supply 100-200nm) can absorb a large number of neutrons without forming any radioisotopes, so it is an ideal neutron absorber in nuclear power plants, and neutron absorbers are mainly Controls the rate of nuclear division. Boron carbide is mainly made into controllable rods in nuclear reactors, but sometimes it is made into powder to increase the surface area. During the Chernobyl nuclear accident in 1986, Russia finally stopped the chain reaction in the reactor after dropping nearly 2,000 tons of boron carbide and sand.

2. Abrasive materials
Since boron carbide (supply 100-200nm) has been used as a grit abrasive a long time ago. Due to its high melting point, it is not easy to be cast into artificial products, but it can be processed into simple shapes by melting powder at high temperature. It is used for grinding, grinding, drilling and polishing of hard materials such as cemented carbide and precious stones.

3. Coating paint
Boron carbide (supply 100-200nm) can also be used as a ceramic coating for warships and helicopters.

4. Nozzle
In the arms industry, it can be used to manufacture gun nozzles. Boron carbide (supply 100-200nm), extremely hard and wear-resistant, no reaction with acid and alkali, high/low temperature resistance, high pressure resistance, density ≥2.46g/cm3; microhardness ≥3500kgf/mm2, flexural strength ≥400MPa , the melting point is 2450 ℃. Because of the above characteristics of wear resistance and high hardness of boron carbide nozzles, boron carbide sandblasting nozzles will gradually replace known sandblasting nozzles of cemented carbide/tungsten steel and silicon carbide, silicon nitride, alumina, zirconia and other materials.
