It is produced from quartz sand and high quality anthracite under high temperature in and electric resistance furnace

Tips: Silicon Carbide (SiC) is produced in an electric furnace at temperatures in excess of 2200 Celsius. SiC is produced by fusing coke and high purity silica sand. The result is the formation of SiC crystals which are very hard. SiC also has a very high thermal conductivity and is very strong at elevated temperatures.

F type Black SiC: We offer F TYPE black silicon carbide powders for the abrasive wheel, slurry, refractory and ceramic industries. Abrasive black silicon carbide powders specifically manufactured to be used for general abrasive applications in bonded abrasive tools, lapping and polishing processes. With a lower hardness and abrasive capacity than diamond or boron carbide, it is widely used for grinding nonferrous materials, finishing tough and hard materials, as well as filling up ceramic parts due to its lower cost. It is commonly used in the following applications:

Common Uses:

Silicon carbide powders are used heavily in ceramic, metal lapping, and polishing applications: Slicing of silicon carbide wafers Rock and stone polishing and engraving Slicing, lapping, and polishing glass and germanium wafers Lapping of piston rings and gears Grinding of nonferrous materials Finishing tough and hard materials Bonded abrasive tool applications

Sizes Available: Grit sizes range from coarse grades down to a 2000 mesh size.
