Silicon carbide, more commonly referred to as corundum, is an inorganic chemical compound composed of silicon and carbon atoms that occurs naturally as the rare mineral moissanite but has been mass produced since 1893 for use as an abrasive and ceramic production such as car brake pads or bulletproof vests. Cubic SiC is produced through the Lely process, in which a granite crucible is heated at high temperatures to sublimate silicon carbide powder before it’s deposited onto graphite at a lower temperature. What is Silicon Carbide? Silicon Carbide (SiC) is an alloy composed of silicon and carbon joined together by strong covalent bonds, crystallizing into hexagonal structures with wide band-gap …

Silicon carbide rod is a non-metal high-temperature electric heating element commonly used in tunnel kilns, roller kilns, glass kilns, vacuum furnaces and muffle furnaces as well as other forms of electric heating equipment. It offers superior working temperature stability as well as resistance against oxidation and corrosion damage. When replacing a silicon carbide rod that has broken, save and use all unbroken rods together (to prevent mixing new with old). This can help improve heating uniformity and furnace efficiency. High-temperature resistance Silicon carbide rods are ideal for these applications due to their low coefficient of expansion, good chemical stability and hard and brittle texture, which make it resistant to sudden …
