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.Boron Carbide is one of the hardest man-made materials available in commercial quantities that has a finite melting point low
enough to permit its relatively easy fabrication into shapes. Some of Boron Carbide’s unique properties include: high hardness,
chemical inertness, and a high neutron absorbing cross section.
