Properties of Boron Carbide

Overview of boron carbide B4C powder

Boron carbide, also known as black diamond, is an organic substance with the molecular formula B₄C, usually gray-black micropowder. Boron carbide is one of the three hardest materials known, the other two being diamond and cubic boron nitride.

Properties of Boron Carbide

Boron carbide does not react with acid-base solutions and has high chemical potential, neutron absorption, wear resistance and semiconductor conductivity. It is one of the most acid-stable substances and is stable in all concentrated or dilute aqueous acids or bases. Boron carbide is basically stable below 800 ℃ in the air environment.

The hardness of boron carbide is lower than that of industrial diamond, but higher than that of silicon carbide. Compared to most pottery, boron carbide is less brittle. Boron carbide has strong chemical resistance and is not corroded by hot hydrogen fluoride and nitric acid. Soluble in molten alkali, insoluble in water and acid.

Application of boron carbide B4C powder

Controlled nuclear fission: can absorb a large number of neutrons without forming any radioactive isotopes. It is an ideal neutron absorber for nuclear power plants. Neutron absorbers primarily control the rate of nuclear fission. Boron is mainly used in the field of nuclear reactors as controllable rods, but sometimes into powders due to increased surface area.

Abrasives: Because boron carbide has long been used as a coarse abrasive. Due to its high melting point, it is not easy to cast into man-made products, but the powder can be smelted into simple shapes. high temperature. For grinding, grinding, drilling and polishing of hard materials such as carbide and gemstones.

Coating coatings: Boron carbide can also be used as ceramic coatings for warships and helicopters. It is lightweight and resists penetration of armor-piercing projectiles through the thermocompression coating, forming an overall defensive layer.

Nozzles: Boron carbide can be used as spray gun nozzles 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 manufacture metal borides and smelt sodium boron, boron alloys and special welding.
