Black Silicon Carbide Specifications
- Black Silicon Carbide sic 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 sic is greater than fused alumina but less than synthetic diamond.
- Black silicon carbide’s mechancial intensity is greater than fused alumina, but is brittle and very sharp.
- Black silicon carbide sic has some electrical and heat conductivity.
- Black silicon carbide sic is typically used for machining or finishing cast iron ,non-ferrous metals, stone, leather, rubber, and other materials where sharp cutting characteristics are important.
- Black Silicon Carbide sic is also used widely as a refractory material or metallurgical additive.
