Boron carbide
The organic material B4C is also called black diamond. This substance, which usually comes in the form of gray-black nanopowder, has a formula molecular. Boron carbide ranks third in the world’s hardest materials, alongside diamond and cubic boron oxide.
The hardness is lower for boron carbide than it is for industrial diamonds, but higher than the silicon carbide. Boron carbide is less fragile than most pottery. Boron carbide resists corrosion by hot hydrogenfluoride, nitric and other acids. It is soluble with molten alkali but insoluble with water and acid.
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 absorber is also responsible for controlling the rate at which nuclear fission occurs. Boron carbide, which is used in nuclear reactors as a controllable bar, is sometimes made into powder due to the increased surface area.
During Chernobyl’s nuclear accident, Russia dropped sand and nearly 2,000 tonnes of boron-carbide, which stopped the chain reactions in the reactor.
Abrasive material
The boron carbide is a very old abrasive. Due to its high melting point it is difficult for it to be cast in artificial products. However it can be processed by smelting powder at high temperatures into simple shapes. It is used for grinding and polishing of hard materials, such as gemstones and cemented-carbide.
Coating paint
Boron carbide may also be used to coat warships or helicopters. It is light weight and resistant to armor-piercing bullets.
Nozzle
It is used in the manufacture of gun nozzles for the munitions sector. Boron carbide has a high wear resistance and is resistant to acids and alkalis. It can also withstand high pressures and temperatures.
Due to its high hardness and wear resistance, boron-carbide sandblasting needles will gradually replace the existing sandblasting tools made of silicon carbide/tungsten and cemented carbide/tungsten and silicon nitride.
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: Its Properties
Boron carbide has a very high chemical potential. It is also resistant to wear and semiconductor conductivity. It is one the most stable substances in acid, and it is stable even when diluted or concentrated. Boron carbide remains stable in an atmosphere below 800degC.The hardness is lower for boron carbide than it is for industrial diamonds, but higher than the silicon carbide. Boron carbide is less fragile than most pottery. Boron carbide resists corrosion by hot hydrogenfluoride, nitric and other acids. It is soluble with molten alkali but insoluble with water and acid.
