Boron Carbide for Ceramic

BORON CARBIDE ( the structural formula is B4C, and the molecular weight is 55.26 ) is a nonmetallic material for high-performance structuring ceramics. It is also considered the material for high-performance functioning ceramics. It is one of the hardest Man-Made materials (only near upon diamond and cubic boron nitride), its hardness with Mohs hardness 9.36, its density 2.52 g/cm3, and melting point at 2450 ℃. The material possesses properties of endurance, low temperature, no reaction with either acids or alkalis; it also possesses the specialty properties of light quality, high hardness, semi-conductivity, etc. so that it is widely applied as following: Boriding refractory, ion transfuse, lilm layer as well as grinding, polishing, drilling hard metal alloys, jewels, etc. Meanwhile, it is the primary material for the wear-resisting parts, precise meter-age element, precise spray nozzle, sealed washer smelting boron steel, boron alloy, etc. It possesses the characteristic of absorbing the neutron for boron, so boron carbide is also used as the primary boric material for reaction speed adjusting bar in a nuclear reactor.

Boron Carbide for Ceramic Applications

  • Boron carbide for ceramics is applied widely in industries as wearing resistant materials, abrasives. As an abrasive, it is used in powdered form in the lapping (fine abrading) of metal and ceramic products, though its low oxidation temperature of 400–500° C (750–930° F) makes it unable to withstand the heat of grinding hardened tool steels.
  • Its hardness, together with its very low density, has found application as a reinforcing agent for aluminum in military armor and high-performance bicycles. Its wear resistance has caused it to be employed in sandblasting nozzles and pump seals.
  • Its ability to absorb neutrons without forming long-lived radionuclides makes it attractive as an absorbent for neutron radiation arising in nuclear power plants and from anti-personnel neutron bombs. Nuclear applications of boron carbide include shielding, control rod, and shut down pellets. Within control rods, boron carbide is often powdered to increase its surface area.
