Product Description
Boron carbide, alias black diamond, formula B4C, usually black powder. It is one of the hardest three materials known. (the other two are diamonds, cubic boron nitride), used for armor, bullet proof clothing and many industrial applications of tank cars. Its Mohs hardness is 9.3.
The application of Boron Carbide Powder B4C
-Anti chemical pottery;
-wear-resistant tools;
-Used in double-face grinding of LED and thinning and polishing of sapphire based LED extending plates,national defense industry, nuclear industry refractories industry and other engineering ceramic materials, welding materials etc.
