The Properties And Application of boron carbide

What is boron caride?

Boron carbonide also known as black-diamond, is a powder with a molecular formula B4C. This usually results in a greyish-black color. It is one the three most hard materials (the others being diamond and cubic boron nutride) and it is used in body armor, tank armor, and other industrial applications. Its Mohs Hardness is 9.3.

Due to its low density, strength, high stability, and high chemical stability, Useful in ceramic reinforced phase, wear-resistant materials and reactor neutron absorbers. Because it’s easier and more affordable to make than cubic boron, diamond, or even cubic boron, boron carbonide is widely utilized. Boron carbide can sometimes replace diamonds and it is used for grinding, drilling, and other purposes.

Application of Boron carbide
1.Control nuclear fission
Boron carbide has the ability to absorb large quantities of neutrons while not forming radioisotopes. This makes it an ideal neutron absorber in nuclear power stations. The neutron absorbers control nuclear fission’s rate. Although it can usually be made into rods in the reactor yard, some people make powdered Boron Carbide due to the larger surface area.

Russia lost almost 2,000 tonnes of boron carbide sand and nearly 3,000 tons of other materials in 1986’s Chernobyl nuclear incident. Then, the reactor finally shut down.

2.Abrasive material
The use of boron carbide as coarse abrasive materials has existed for quite some time. Because of its high melting point it is hard to make artificial products from it. But, you can melt the powder at high heat to transform it into simpler shapes. This is useful for polishing and drilling hard materials, such as precious and cemented stones and cement carbide.


Boron carbide can be used to coat warships or helicopters with ceramics. The material is lightweight, and it can resist armor-piercing bullets.

You can use it as an arm industry gun nozzle. Boron carbide can be used as a gun nozzle in the arms industry. It has an extremely high wear resistance and density.

Due to its high wear resistance, high hardness and durability, the boron-carbide sandblasting device will replace existing cemented caride/tungsten steel, silicon carbide, silica nitride and aluminum oxide sandblasting devices.

Boron carbide may also be used for the production of metal borides as well as smelting sodium, boron alloys and special welding.
