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 silicon carbide, but is less hard than industrial diamond. Ceramics made of boron-carbide are less fragile than other ceramics.
Boron carbide powder has a high stability to acids and alkali solutions. Boron carbide in an atmosphere is essentially stable below 800degC. The boron oxide that is formed when it is oxidized at higher temperatures, is lost in gas phase. This leads to its instability.
What uses does boron carburide have?Boron carbide is a powder with low density and high strength. It also has good chemical stability, a high temperature stability, and possesses favourable thermal stability. It’s used as a ceramic reinforcing phase, in materials that are resistant to wear, and in armor, neutron absorbers for reactors, and other lightweight products. As boron carbide can be easily manufactured and has a low cost, it is used more than diamonds and cubic boron. It can be used to replace expensive diamonds at certain locations and is often used for grinding, drilling, and grinding.
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 processed by melting the powder at a high temperature into simple shapes. Boron carbide powder can be used for grinding and drilling hard materials, such as gemstones and cemented carbide.
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.
Due to their high hardness and wear resistance, boron nitride nozzles will replace other materials like silicon carbide/tungsten and cemented carbide/tungsten.
Boron carbide powder can also be used for the production of metal borides as well as boron alloys and welding.
