What is Boron Carbide?

Boron carbonide also known as black-diamond, is a powder with a molecular formula B4C. This usually results in a greyish black powder. 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 wear-resistant material, ceramic reinforced phase, particularly in light armor, and reactor neutron absorbers. Boron carbide has a lower cost of production than cubic boron, which is why it is widely used. Boron carbide can sometimes replace diamonds and it is used for grinding, drilling, and other purposes.

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 formed into rods in the reactor yard, the greater surface area means that Boron Carbide may also be powdered.

Russia released nearly 2,000 tonnes of boron carbide sand and other materials in 1986 to prevent the Chernobyl nuclear catastrophe.

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 can not be cast into any artificial products. But, it can still be processed by high-temperature melting it at high temperature to make simple 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 excellent durability, the boron-carbide sandblasting device will eventually 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.
