Silicon carbide is produced through melting silica sand with carbon sources such as coal at high temperatures; this process is known as Lely’s method. Silica sand and graphitized petroleum coke carbon are the primary raw materials utilized in manufacturing. Additional auxiliary materials, like sawdust and salt, may also be utilized but do not contribute directly to chemical reaction. Cold Isostatic Pressing Silicon carbide production begins with the compaction process. Raw materials are mixed with binder and then compacted by extrusion or cold isostatic pressing into blocks or plates that will later be sintered under vacuum in order to give these finished parts their hardness and chemical resistance. Die compaction involves …
