Silicon carbide powder for steelmaking
Silicon carbide is a man-made material 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.
