    Difficult to sintered ceramic - boron carbide


    Boron carbide (B4C) has a strong b-b and b-c covalent bond, which is one of the most difficult ceramics to sintering. But since it has low density (right to 2.52 m - 3), high melting point (2450 oc), high hardness (Hv microhardness value about 30 GPa, second only to diamond and cubic boron nitride),......

    Boron carbide application


    Boron carbide is a solid solid that is harder than silicon carbide or tungsten carbide, and the alloy material made of aluminum is called synthetic diamond, which was used as a coarse abrasive material long ago. Although its own melting point is high, it is not easy to cast artificial products, but ......
