Boron carbide ceramic

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.
