What are boron carbid properties?
Boron carbide powder Also known as black Diamond, this organic substance is a powder with the chemical formula B4C. It’s usually gray or black. It is among the three hardest substances known (the two others being diamond and cubic boron-nitride).Boron carbide looks like a shiny black crystal. Boron carbide has a harder surface than industrial diamonds, but is softer than silicon carbide. Compared to other ceramics, boron-carbide ceramics are less fragile.
Boron carbide powder has a high stability to acids. It is also stable in all concentrated and dilute alkali or acidic aqueous solutions. Boron carbide in an atmosphere is essentially stable below 800degC. The boron oxide that is formed when it oxidizes at a high temperature is lost during the gas phase. This leads to its instabilities and oxidation into carbon dioxide and trioxide.
What uses does boron carburide have?
Boron carbide is a powder with low density and high strength. It also has good chemical stability, high temperature stability, and high temperature stability. It’s used as a ceramic reinforcing phase, in materials that are resistant to wear, and in armors, neutron absorbers for reactors, etc. As boron carbide can be easily manufactured and has a low cost compared to diamond and cubic Boron Nitride, it is used more. It can be used to replace expensive diamonds at certain locations and is often used for grinding, drilling, and grinding.Abrasive material
The boron carbide was used as an abrasive coarse material for many years. Due to its high melting point it is difficult for it to be cast in artificial products. However it can be formed into simple shapes through smelting at high temperatures. Boron carbide powder can be used for grinding and drilling hard materials, such as gemstones and cemented carbide.
Coating paint
Boron carbide may also be used on warships or helicopters as a ceramic surface. It is lightweight with the ability to resist armor-piercing bullets.
Nozzle
Due to their wear resistance and hardness, boron nitride nozzles, zirconia, alumina, silicon carbide and cemented carbide/tungsten will be gradually replaced by boron nitride nozzles.
Other
Boron carbide powder can also be used for the production of metal borides as well as boron alloys and welding.
