Boron carbide It is an inorganic substance that has the chemical formula B4C. It’s 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, neutron absorbance, 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 carbide formed from its oxidation is lost to the gas phase.
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 to replace diamonds and is widely used in many aspects.

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 neutrons absorber is what controls the nuclear fission rate. 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.

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 in the production of metal borides.
