Silicon carbide (SiC) is an inert material with excellent thermomechanical properties for many optoelectronic, structural, and ballistic appliions. However, manufacturing SiC components is challenging due to the high temperatures (> 2000 deg C) and pressures (1000-2000
The industrial process performed by Navarro SiC for the production of silicon carbide uses Acheson method, based on the following chemical reaction: SiO 2 + 3·C -> SiC + 2·CO A mixture of high purity sand or quartz and petroleum coke chemically react in Acheson furnace at temperatures up to 2,500 °C.
Silicon carbide (SiC) is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process). Depending on the exact reaction conditions the resulting silicon carbide is either a fine powder or a bonded mass that requires crushing and milling to produce a usable feedstock.
