boron carbide B4C f400 f500 f600 f800 china manufacturer
WHAT’S BORON CARBIDE
Boron carbide is produced by high temperature smelting boric aid and carbon materails in electric furnaces.
Boron carbide has theoretic density of 2.52g/cm3;Boron carbide has melting point of 2450 C;Boron carbide micro hardness is 4950 kgf/mm2
Boron carbide hardness is just lower than diamond and cubic B4C.
Boron carbide have high temperature resistance,acid and alkali resistance,high strengh,good chemical stability,and low specific weight,so Boron Carbide B4C is widely used in many new materials fields.

APPLICATION OF BORON CARBIDE
- 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.
- 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.
- Engineering ceramic materials
Boron carbide can make nozzles for sandblasting machines
High-pressure water cutting machine nozzle
Seal ring,Potter mold and so on.
- 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.
- 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.
- 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.
