China factory supply b4c boron carbide powder abrasive for polishing

 

 

Product description:

     

    Boron carbide is the hardest of the conventional abrasives. Boron carbide has following unique features: neutron absorbing, of semi-conductivity, low thermal conductivity, high grinding efficiency and no reaction with either acids or alkali etc. Boron carbide steel, jewel, hard ceramic and other hard materials, and to manufacture wear-resisting parts, metal cutting tools, nozzles and neutron-absorbing rods, used as metal additive for compound materials for military planes and as raw materials for metal boride, metal ceramic, boron steel, boron alloy and for special welding and refractory materials.
