Silicon carbide is a man-made material, also called as SIC, manufactured through heating silica sand and carbon to high temperatures in the Acheson furnace technique. Silicon carbide is an extremely hard material (Mohs hardness 9.25), is chemically inert and does not melt. Silicon Carbide has a high thermal conductivity, a low coefficient of thermal expansion, is thermal shock and abrasion resistant and has strength at high temperatures. Silicon carbide's varied properties make it an effective material in many different applications. 

Silicon carbide contains two common basic varieties: black silicon carbide and green silicon carbide. Black silicon carbide contains sic about 95%, so the toughness is higher than green silicon carbide. It is widely used for processing low tensile strength material like glass, ceramics, stone, refractory material, cast iron and nonferrous metal etc. Green silicon carbide contains sic about 97% above with good self-sharpening, so it is used for processing hard alloy, titanium alloy and optical glass as well as cylinder jacket and fine grinding cutting tools.
