Boron carbide Also known as black Diamond, this inorganic substance has a formula B4C and is usually a gray-black powder. It is one the hardest materials (after diamonds and cubic boron Nitride).

Boron Carbide Properties

Boron carbide has a very high chemical potency, as well as a neutron absorber, wear resistance, and semiconductor conductivity. Boron carbide, one of most stable substances for acid, is stable in any concentrated or diluted acid or alkali solutions.
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 silicon carbide. Boron carbide has low density and high strength. It also has good chemical stability, and is resistant to high temperatures.

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 is commonly used for grinding, drilling, and other applications.

Control nuclear fission
Boron carbide absorbs a large amount of neutrons while forming no radioactive isotopes. This makes it an ideal neutron absorption material in nuclear power stations. The neutron absorption material is also used to control nuclear fission. Boron carbide, which is used in nuclear reactors, is usually made in a controlled rod shape. But sometimes it’s made as a powder to increase the surface area.

Abrasive material
The high melting temperature of boron carbide makes it difficult to cast into artificial shapes. However, it can be easily shaped by smelting powder at high temperatures. It is used for grinding, polishing, drilling, and grinding hard materials like cemented carbide or gemstones.

Coating paint
Boron carbide may also be used to coat warships or helicopters. It is light and resistant to armor-piercing bullets.

It is used in the manufacture of gun nozzles for the munitions sector. Due to its high hardness and wear resistance, the boron-carbide sandblasting node will replace the existing sandblasting materials such as silicon carbide/tungsten, cemented carbide/tungsten, alumina and zirconia.

Boron carbide also is used in the production of metal borides.
