What boron-carbide properties are there?
Boron carbide powder
Also known as black diamond, a organic substance that has a chemical composition of B4C is often gray-black powder. It is one of three hardest materials known, the other two being diamond and cubic-boron nitride.
Boron carbide, a hard black shiny crystal, is known as. Boron carbide is harder than an industrial diamond but more hard than silicon carbide. Boron carbide ceramics have a lower rate of fracture than other types of pottery.
Boron carbide is one of most stable acid substances. It is stable in all concentrated and dilute acids as well as alkali aqueous solutions. Boron carbide is stable in air temperatures below 800°C. The boron dioxide that forms from the oxidation at a higher temperature is lost to the gas phase. It can then become unstable and oxidized to carbon dioxide or boron trioxide.
What is the use of boron caride?
Boron carbide powder features low density, high strength and high temperature stability. It is used in ceramic reinforcing phase, wear-resistant materials, and lightweight armor. It is also cheaper than diamond and cubic-boron nitride and is therefore more widely used. It can be used to replace expensive diamonds in certain places.
Abrasive material
Boron carbide has long been used as an abrasive material. Although it has a high melting point, it cannot be cast into any artificial products. However, it can be made into simple shapes by heating the powder. Boron carbide is used for drilling, grinding, drilling, and polishing hard materials, such as gemstones and cemented carbide.
Coating paint
Boron carbide is also a suitable ceramic coating for warships, helicopters, and other aircraft. It is lightweight and resists armor-piercing bullets. The hot-press coating forms an integral defense layer.
Nozzle
The boron-carbide nozzles have wear resistance and high hardness. They will eventually replace cemented caride/tungsten steel, silicon carbide and silicon nitride.
Other
Boron carbide is used in the manufacture and smelting of metal borides, boron alloys, special welding, and in the manufacture sodium boron.
