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.

Silicon carbide powder including black silicon cabide and green silicon carbide,different color,black one is more wear resist,green one is harder,both nice stone polishing powder.
