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, مقاومة للتآكل, high temperature resistant, الموصلية الحرارية المنخفضة, high modulus of elasticity, it is ideal for a wide variety of applications.
