How silicon is made material making history used

When silicon is heated it reacts with the halogens fluorine chlorine bromine and iodine to form halides It reacts with certain metals to form silicides and when heated in an electric furnace with carbon a wear resistant ceramic called silicon carbide is produced Hydrofluoric acid is the only acid that affects silicon

Silicon Carbide Production Process Fiven

Silicon Carbide Production Process While alternative production methods have emerged for selected high purity silicon carbide over the last years the majority of SiC used today is produced using the so called Acheson process Silicon carbide SiC is a synthetic mineral most commonly produced in electrical resistance furnaces by the Acheson process named after the American EG Acheson

SiC Production Process Washington Mills

Silicon carbide crude is produced by mixing silica SiO2 with carbon C in an electric resistance furnace at temperatures around 2500 C The chemical reaction in the SiC process may be represented by the formula SiO2 3C SiC 2CO Washington Mills employs two different manufacturing methods for producing SiC crude the traditional Acheson process and large furnace technology
