Acheson process - Wikipedia

The first commercial plant using the Acheson process was built by Acheson in Niagara Falls, New York, where hydroelectric plants nearby could cheaply produce the necessary power for the energy intensive process. By 1896, The Carborundum Company was producing 1 million pounds of carborundum. Many current silicon carbide plants use the same basic design as the first Acheson plant.

Silicon Carbide (SiC) Properties and Applications

BackgroundDiscoveryKey PropertiesCommercial Grades of Silicon CarbideSilicon 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.Several hundred structures of silicon carbide (polytypes) have been identified which have different stacking arrangements for the silicon and carbon atoms.
