The current method for producing silicon involves using quartz and carbon. Quartz consists of one silicon atom and two oxygen atoms. To dissolve the bond between the two, solid carbon (coal, coke) is used as a reducing agent. The process requires a temperature of 1700 degrees and takes place in an electric arc furnace.
