Introduction
Boron Carbide(B4C) is made of boric acid and carbon materials by high temperature smelting, which is sometimes called “black diamond” for its hardness and chemical resistance.
Boron carbide is applicable to a wide range of uses and performs well in the application fields of refractory materials against oxidation, grinding, polishing, lapping, wire sawing, waterjet cutting, bulletproof materials and nuclear industry.
