high strength, corrosion-resistant, high-temperature-resistant and stable chemical nature,wide range of applications B4C (Boron Carbide) is melted from boric acid and powdered carbon in electric furnace under high temperature. Its density is 2.52g/cm3, melting point 2450C; micro hardness 4950kgf/mm2, only next to diamond and cubic boron nitride (CBN). Due to its high strength, low specific gravity, corrosion-resistant, high-temperature-resistant and stable chemical nature, it is ideal for a wide range of applications.
Application
It is used to make ceramic anti-ballistic armour plating such as
---the small arms protective insert-a plate used in bullet-resistant vest,
---the ceramic tiles or plates used for the armoured cockpits of military air-planes, and the spall liners used in the tanks and modern armoured personnel carriers.
Used in the nuclear industry as
---to make control rods and shut down pellets for nuclear reactor
---to make tiles or plates or use the B4C powder for neutron absorber (high B10 content) for radiation protection, or mixed with concrete for shielding protection/
Used to make other ceramic products such as
---Grit blasting nozzles,
---High-pressure water jet cutter nozzles,
---Seal ring,
---Ceramic tolling dies.
Used in welding rods for improvement of wear resistance of surface.
Used in refractory industry: as antioxidant additives in magnesia carbon bricks.
It is an abrasive material in lapping and polishing applications, and also as a loose abrasive in cutting applications such as in water jet cutting. It can be also used for dressing diamond tools.
