Silicon carbide manufacturing process
Silicon carbide (SiC) is a compound of silicon and carbon with a chemical formula of SiC. The simplest manufacturing process for producing silicon carbide is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1600C (2910F) and 2500C (4530F).
