The Properties And Uses of Boron Carbide Powder

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 diamond but is softer than silicon carbide. Compared to other ceramics, boron-carbide ceramics are more fragile.

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 a high temperature is lost during the gas phase. This leads to its instabilities and oxidation into carbon dioxide and trioxide.

What are the uses of boron carbide?

Boron carbide is a powder with low density and high strength. It also has good chemical stability, is resistant to high temperatures, and has a high degree of temperature stability. It’s used as a ceramic reinforcing phase, in materials that are resistant to wear, and in armor, neutron absorbers for reactors, etc. 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.

Abrasive material
The boron carbide was used as an abrasive coarse material for many years. Due to its high melting point it is not easily cast into artificial items, but can be processed by melting the powder at a high temperature. Boron carbide powder can be used to polish, grind, drill, and grind 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, alumina zirconia, 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 smelting sodium-boron, boron alloys and special welding.
