  • Our Silicon Production Process Mississippi Silicon

    The basic process for producing silicon has remained unchanged for decades: quartz or gravel (SiO2) is blended with a carbon source and superheated in a submerged arc furnace. As the mix heats, the carbon reacts with the oxygen in the quartz and forms CO gas, thereby reducing the quartz to 99% silicon in molten form.

    OverviewChemistry and compoundsHistoryCharacteristicsOccurrenceProductionApplicationsBiological role

    Crystalline bulk silicon is rather inert, but becomes more reactive at high temperatures. Like its neighbour aluminium, silicon forms a thin, continuous surface layer of silicon dioxide (SiO2) that protects the metal from oxidation. Thus silicon does not measurably react with the air below 900 °C, but formation of the vitreous dioxide rapidly increases between 950 °C and 1160 °C and when 1400 °C is reached, atmospheric nitrogenalso reacts to give the nitrides SiN and Si3N4.
