Boron carbide
, or black diamond, has a formula of B4C. It’s usually a gray-black powder. It is one the hardest materials (after diamonds and cubic boron Nitride).
Boron carbide, in an atmosphere with low temperatures, is stable. The boron oxide that is formed when it oxidizes at a high temperature is lost to the gas phase. It then oxidizes into carbon dioxide and borontrioxide.
The Mohs hardness for boron carbide, at 9.5, is third-hardest after cubic boron and diamond. Its hardness is also higher than that of silica carbide. Boron carbide has low density and high strength. It also has good chemical stability, a high temperature resistance, and a high level of heat stability.
Control nuclear fission
Boron carbide absorbs a large amount of neutrons and does not form any radioactive isotopes. It is therefore an ideal neutron absorption material in nuclear power plants. The neutron absorber is also responsible for controlling the rate of fission. Boron carbide, which is used in nuclear reactors, is usually made in a controlled rod shape. But sometimes it’s made into powder form because of its increased surface area.
Abrasive material
The high melting temperature of boron carbide makes it difficult to cast into artificial shapes. However, the powder is easily shaped by smelting it at high temperatures. It is used for grinding and drilling hard materials, such as gemstones and cemented carbide.
Coating paint
Boron carbide may also be used to coat warships or helicopters. It is light and resistant to armor-piercing bullets.
Nozzle
It is used in the manufacture of gun nozzles for the munitions sector. Due to its wear resistance and hardness, boron-carbide sandblasting needles will gradually replace known sandblasting needles made of silicon carbide/tungsten and cemented carbide/tungsten.
Other
Boron carbide also is used to make metal borides. It can be used for smelting sodium-boron, boron alloys, or special welding.

Boron Carbide Properties
Boron carbide has a very high chemical potency, neutron absorbance, wear resistance, and semiconductor conductivity. Boron carbide, one of most stable substances for acid and alkali solutions is stable at all concentrations or dilutions.Boron carbide, in an atmosphere with low temperatures, is stable. The boron oxide that is formed when it oxidizes at a high temperature is lost to the gas phase. It then oxidizes into carbon dioxide and borontrioxide.
The Mohs hardness for boron carbide, at 9.5, is third-hardest after cubic boron and diamond. Its hardness is also higher than that of silica carbide. Boron carbide has low density and high strength. It also has good chemical stability, a high temperature resistance, and a high level of heat stability.
Boron carbide Applications
Boron carbide has been used to make wear-resistant materials and ceramic reinforcing phases. It is also used in the manufacture of lightweight armors, reactor neutron absorbers, etc. Boron carbide, because it is low-cost and easy to make, is widely used. It can be used in place of expensive diamonds and is widely used for grinding, drilling, and other aspects.Control nuclear fission
