boron carbide b4c 60-150mesh

boron carbide b4c 60-150mesh

Product Description

Hard, black, shiny crystals. Hardness is lower than industrial diamond, but higher than silicon carbide. Fragility is lower than most pottery. Has a large thermal energy neutron capture cross section. Strong chemical resistance. Not subject to the attack of hot hydrogen fluoride and nitric acid. Soluble in molten alkali, insoluble in water and acid.

 Application

1.refractories

Boron carbide can be used for low carbon magnesium carbon brick and castable.

Boron carbide is used in the key parts of high temperature and erosion resistance in the steel industry.

Such as ladle, tap hole (water mouth), stopper, etc.

Boron carbide acts as an antioxidant inside.

2.National Defense Industry

Boron carbide can be used to make bulletproof materials, such as bulletproof plates, ceramic bulletproof tiles for pilot cabins, and ceramic bulletproof plates for tanks.

Boron carbide can be used as a nozzle for guns and cannons in the arms industry.

3, engineering ceramic materials

Boron carbide can make nozzles for sandblasting machines

High-pressure water cutting machine nozzle

Seal ring

Potter mold and so on.

4, general industry

Boron carbide can be used to make high-grade wear-resistant electrodes,

Boron carbide is used as abrasive polishing material, abrasive for water cutting and diamond abrasive correction material;

Boron carbide is used for high-precision polishing and grinding in the jewelry industry.

5, electrical performance applications

Boron carbide-graphite thermocouple is composed of graphite tube, boron carbide rod and boron nitride bushing between the two. Under inert gas and vacuum, the use temperature is up to 2200 ° C. Between 600 and 2200 ° C, the potential difference has a good linear relationship with temperature.

6.Application as a chemical raw material

Boron carbide powder is activated by halogen. It can be used as boronizing agent for steel and other alloys to boronize steel surface. It can also be used as non-metal additive for some metal-based friction materials. In the reduction-chemical method for preparing boride powder, boron carbide can be used as a boron source to obtain TiB2, ZrB2, CrB2 and other powders.
