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 a little lower than the industrial diamond but higher than silicon carbide. Boron carbide is more 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 and does not form any radioactive isotopes. It is therefore an ideal neutron absorption material in nuclear power plants. The neutrons absorber is what controls 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, polishing, drilling, and grinding hard materials like cemented carbide and gemstones.
Coating paint
Boron carbide may also be used to coat warships or helicopters. It is light weight and resistant to armor-piercing bullets.
Nozzle
The munitions sector can make use of it for gun nozzles. Boron carbide has a high wear resistance, is resistant to high pressure, and does not react with acids or alkalis.
Due to its high hardness and wear resistance, the boron-carbide sandblasting needle 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 in the production of metal borides as well as boron alloys and special welding.

Boron Carbide: Its Properties
Boron carbide has high chemical potential. It is also resistant to wear and semiconductor conductivity. It is one of most stable substances for acid, and stable in any concentrated or diluted acid or alkali solutions. Boron carbide remains stable in an atmosphere below 800degC.The hardness is a little lower than the industrial diamond but higher than silicon carbide. Boron carbide is more 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.
