Boron carbide features:
Boron carbide possesses high purity, narrow range particle size distribution, larger specific surface area and so on;
The melting point of Boron carbide is up to 2350oC, boiling point higher than 3500℃ hardness up to 9.3, flexural strength ≥ 400Mpa;
Boron carbide does not react with acid and alkali solution. It has high chemical potential and is one of the most stable materials to acid. Also, it has properties of anti-oxidation, high temperature resistant, high strength, high grinding efficiency, high hardness, high elastic modulus, high wear-resistant, and good self-lubrication characteristics;
Boron carbide has a larger thermal neutron capture cross section, with excellent neutrons absorption property and good anti-radiation performance

Boron carbide applications:
Boron carbide can absorb a large amount of neutrons without forming any radioisotope, so it is an ideal neutron absorber in nuclear power plants, and neutron absorbers mainly control the rate of nuclear fission. Boron carbide is mainly made into a controllable rod in the nuclear reactor field, but sometimes it is powdered because of the increased surface area.
Boron carbide has long been used as a coarse sand abrasive material. Since it has a high melting point and is not easily cast into an artificial product, it can be processed into a simple shape by melting the powder at a high temperature. Used for grinding, grinding, drilling and polishing of hard materials such as cemented carbide and gemstones.
Boron carbide can also be used as a ceramic coating for warships and helicopters. It is lightweight and resistant to the ability of armor-piercing bullets to penetrate the hot-pressed coating into an integral layer.
Boron carbide can be used in the arms industry to make gun nozzles. Boron carbide, extremely hard and wear-resistant, does not react with acid and alkali, high/low temperature resistance, high pressure resistance, density ≥2.46g/cm3; microhardness ≥3500kgf/mm2, flexural strength ≥400Mpa, melting point is 2450°C.
Because of the above-mentioned high wear resistance of boron carbide nozzles, boron carbide blasting nozzles will gradually replace known cemented carbide/tungsten steel and sandblasting nozzles made of silicon carbide, silicon nitride, alumina, zirconia, etc. .
Boron carbide is also used in the manufacture of metal borides and in the smelting of sodium borates, boron alloys and special welds.
