Silicon seduced from silica Nature

WebThe 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. WebSilicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. on the chairs
