Black Silicon Carbide  1-10mm  90%

It is produced in a high temperature electric resistance-type furnace from a mixture of quartz sand and petroleum coke. The hardness of black silicon carbide is greater than fused alumina but less than synthetic diamond. Its mechancial intensity is greater than fused alumina, but is brittle and very sharp. The mineral has some electrical and heat conductivity. Black silicon carbide is typically used for machining or finishing cast iron ,non-ferrous metals, stone, leather, rubber, and other materials where sharp cutting characteristics are important. The mineral is also used widely as a refractory material or metallurgical additive. More detailed specifications can be supplied on your request.
