Black Silicon Carbide For Grinding Wheel
Black silicon carbide is made from quartz sand and smokeless acetylene as the main raw material. It is made via light resistance from hydro metallurgical, it is black opaque body hexagonal crystal and MOHS—hardness the 9.15, which is after diamond and boron carbide with crisp and sharp performance and certain degree of conductive heat.
