The properties and applications of boron carbide

What is boron carbide?

Boron carbide, also known as black diamond, has a molecular formula of B4C and is usually a gray-black powder. It is one of the three hardest materials known (the other two are diamond and cubic boron nitride) and are used in tank armor, body armor and many industrial applications. Its Mohs hardness is 9.3.

Due to its low density, high strength, high temperature stability and good chemical stability. Used in wear-resistant materials, ceramic reinforcement phases, especially light armors, reactor neutron absorbers, etc. In addition, compared with diamond and cubic boron nitride, boron carbide is easier to manufacture and cheaper, so it is more widely used. In some places, it can replace expensive diamonds, and is often used for grinding, grinding, drilling and other applications.

Overview of Boron Carbide:

Boron carbide can absorb a large number of neutrons without forming any radioactive isotopes, so it is an ideal neutron absorber in nuclear power plants. The neutron absorber mainly controls the rate of nuclear fission. Boron carbide is used in nuclear reactors. It is made into a controllable rod shape, but sometimes it is made into a powder due to the increase in surface area.

Application of Boron Carbide:

Control nuclear fission: Boron carbide can absorb a large number of neutrons without forming any radioactive isotopes, so it is an ideal neutron absorber in nuclear power plants. The neutron absorber mainly controls the rate of nuclear fission. Boron is mainly made into controllable rods in the field of nuclear reactors, but sometimes it is made into powder due to the increase in surface area.

Abrasive: Because boron carbide has been used as a coarse abrasive for a long time. Because of its high melting point, it is not easy to cast into man-made products, but it can be processed by smelting powder into simple shapes. high temperature. Used for grinding, grinding, drilling and polishing hard materials such as cemented carbide and gemstones.

Coating paint: Boron carbide can also be used as a ceramic coating for warships and helicopters. It is light in weight and can resist the penetration of armor-piercing projectiles through the hot-pressed coating to form an overall defense layer.

Nozzle: It can be used as a spray gun nozzle in the ordnance industry. Boron carbide is extremely hard and wear-resistant, does not react with acid and alkali, is resistant to high temperature/low temperature, and is resistant to high pressure. Boron carbide is also used to make metal borides and smelt sodium boron, boron alloys and special welding.
