The boron carbide is with high and low temperature resistance, and high grinding efficiency, without reactions to either acid or alkalis. Its not magnetic, and is a good substitute for diamond. Boron carbide is of light weight, with neutron absorbing function and semi- conductivity so that it is used in the military and nuclear industries in addition to boride refractory, ion transfusion, and film layer usage. Furthermore, it can be used for grinding, polishing, and drilling hard metal alloys and jewels. It is the main material for wear-resistant parts, precise meter elements, precise spray nozzles, sealed washer smelting boron steel and boron alloys. Boron carbide is with various excellent physical and chemical prosperities, suitable for the high-tech industrie
