Description:Black silicon carbide 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 mechanical intensity is greater than fused alumina, but is brittle and very sharp. The mineral has some electrical and heat conductivity.
Application:F12-F14, use for sandblasting, rust removal, snagging, heavy duty grinding of steel ingot, leather, salt, floor boards.
F14-F30, use for casting play burr, cutting billet and steel tube, flat kibbling, steel ingot grinding, marble grinding, or as refractory material.
F30-F60, use for surface abrasion, outside&surface grinding, centerless grinding, tool grinding of quenching or no-quenching steel profiles, copper or other hard metal.
F60-F100, use for precision grinding, cutter sharpening, gear grinding, etc.
F100-F240, use for cutter sharpening, rough grinding, precision grinding, thread grinding.
F280-F600, use for precision grinding&thread grinding of instrument and matter an gear products.
F600-F2000, super-precision polishing, mirror polishing, surface lapping, etc.
