Which boron-carbide properties are there? Boron carbonide powder also known as black-diamond, is an organic material with a chemical composition of B4C. It is usually granular gray-black powder. It is known to be one of three most hard materials (the others being cubic boron nutride and diamond).
Boron carbide, a black and shiny crystal, is hard. Boron carbide is harder than an industrial diamond but more hard than silicon carbide. The boron-carbidide ceramics are more fragile than any other type of pottery.
Boron carbide powder, which is one the most stable acid substances, is stable in concentrated and dilute acids as well as alkali aqueous solutions. Boron carbide is stable in low temperatures (less than 800°C) when it’s exposed to air. It is possible to lose the boron dioxide that forms from higher temperatures of its oxidation, which results in instability and oxidation as carbon dioxide and/or boron trioxide.
How do you use boron caride?
Boron carbide has low density, high strength and high temperatures stability. It also exhibits good chemical stability. Boron carbide powder can be used as a wear-resistant material, in ceramic reinforcing phase, and in lighter armors, neutron absorbers, and in other areas such as ceramic reinforcement phases. It is also easier to produce than diamond or cubic boron nutride, making it more widespread. You can use it to replace costly diamonds in certain areas.
Abrasive material Since long time, boron carbide is a common coarse abrasive. Although it has a high melting point it cannot be used to make artificial products. It can however be made into small shapes by heating the powder. Boron carbide is used in grinding, drilling, polishing, and drilling hard materials, such as gemstones and cemented caride.
Coating paint Boron carbide can be used to coat warships or helicopters with ceramics. Boron carbide is lightweight and can resist armor-piercing projectiles. It forms an integral defense coating by hot pressing.
Nozzle The boron-carbide nozzles offer wear resistance and high toughness. They will eventually replace cemented caride/tungsten steel, silicon carbide and silicon nitride.
Other Boron carbide is used to make metal borides as well as smelting sodium and boron alloys, special welding, and other processes.
