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, a neutron absorber, possesses exemplary wear resistance, and is semiconductor conductive. 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 oxidation product is lost to the gas phase and leads to its instabilities and oxidation into carbon dioxide and Boron trioxide.
Its hardness is greater than that of silicon carbide. Boron carbide exhibits low density and high strength. It also has good chemical stability, high temperature resistance, and high temperatures stability.

Boron carbide Applications

Boron carbide has been used to make wear-resistant materials and ceramic reinforcing phases. It is also used for neutron absorbers in reactors, lightweight armor, etc. Boron carbide, because it is low-cost and easy to make, is widely used. It can replace expensive Diamond in some areas and is commonly used for grinding and drilling.

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 absorption material is also used to control the rate of nuclear fusion. 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 melting the powder in 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 wear resistance and hardness, boron-carbide sandblasting needles will gradually replace those made of silicon carbide/tungsten and cemented carbide/tungsten.

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