BORON CARBIDE

Boron carbide is one of the hardest Man-Made materials, only after diamond and cubic Boron Nitride. It is smelted from Boric Acid and Powdered Carbon in electric furnace under high temperature.

Due to its high hardness, high strength, low density, superior corrosion resistance, high temperature resistance, low thermal conductivity and high modulus of elasticity, Boron Carbide is an ideal material for various applications.

Physical Data

  • Color: Black
  • Hardness: 9.36 Mohs  (diamond is 10 Mohs)
  • Theoretical Density: 2.52g/cm3
  • Melting point: 2450℃

Applications

  • Grinding, lapping and polishing Tungsten Carbide, Jewels, Ceramic etc
  • Armor
  • Refractory
  • Nuclear Industry
  • Chemical Additive
  • Solid Fuel
  • Anti-wearing parts in blasting, Sealing, Machinery, Ships, Auto, Dies, Aviation, Aerospace industry

1) Abrasive Grade:
