Overview of boron carbide B4C powder:

Boron carbide has the characteristics of low density, high strength, high temperature stability and good chemical stability. Therefore, it is widely used in wear-resistant materials, ceramic reinforcement phases, especially in lightweight armor, reactor neutron absorbers, etc. In addition, compared with diamond and cubic boron nitride, boron carbide is easy to manufacture and low in cost, so it is more widely used. It can replace expensive diamonds in some places, and is usually used for grinding, grinding, drilling and other aspects.

B4C powder has the characteristics of high purity, small particle size distribution and large specific surface area. B4C powder is a synthetic superhard material with a hardness of 9.46; the microhardness is 56-6200Kg/mm2, the ratio is 252 g/cm3, and the melting temperature is 2250 degrees Celsius.

Application of Boron Carbide B4C Powder:

What are the uses of boron carbide B4C powder?

Control nuclear fission

Boron carbide can absorb a large number of neutrons without forming any radioactive isotopes, so it is an ideal neutron absorber in nuclear power plants, and the neutron absorber mainly controls the rate of nuclear fission. Boron carbide is mainly made into a controllable rod in the nuclear reactor field, but sometimes it is made into a powder because of the increase in surface area.

During the Chernobyl nuclear accident in 1986, Russia dropped nearly 2,000 tons of boron carbide and sand, which eventually stopped the chain reaction in the reactor.

Abrasive material

Because boron carbide has been used as a coarse abrasive material for a long time. Because of its high melting point, it is not easy to be cast into artificial products, but it can be processed into simple shapes by smelting the powder at high temperature. Used for grinding, grinding, drilling and polishing hard materials such as cemented carbide and gemstones.

Coating paint

Boron carbide can also be used as a ceramic coating for warships and helicopters. It is light in weight and has the ability to resist the penetration of armor-piercing projectiles through the hot-press coating to form an integral defense layer.

nozzle

In the munitions industry, it can be used 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, bending strength ≥400MPa, melting point 2450℃.

Because the boron carbide nozzle has the above characteristics of wear resistance and high hardness, the boron carbide sandblasting nozzle will gradually replace the known sandblasting nozzles of cemented carbide/tungsten steel and silicon carbide, silicon nitride, alumina, zirconia, etc. .

other

Boron carbide is also used in the manufacture of metal borides, smelting sodium boron, boron alloys, and special welding.
