Boron carbide is smelted from boric acid and powdered carbon in electric furnace under high temperature. Depending on hardness of 4950kgf/mm2, It is even harder than diamond and cubic boron nitride. Because of their high strength, low density, corrosion resistant, high temperature resistant, low thermal conductivity, high modulus of elasticity, it is ideal for a wide variety of applications.
Characters are as follows:
• Light Density
• High Hardness and Strength
• Erosion Resistance
• High Modulus of Elasticity
• Neutron Absorber
• Low thermal conductivity
