Our Process. 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.
