Silicon does not exist on its own in nature. Most of it is bound with oxygen in materials like sand and quartzite and granite rock. The silicon-oxygen bond in quartz is so stable it can only be broken by white heat! Silicon producers reduce high-grade quartz sand to elemental silicon via a carbo-thermic smelting process: Formula for reducing sand to elemental silicon • This reaction occurs in an electric furnace at <1,400°C . • The carbon monoxide gas (g) leaves the furnace so the silicon cannot react with the carbon monoxide in a reverse reaction to form silicon dioxide. • The molten elemental silicon, which is about 99 percent pure, is then cooled and broken into lumps. • When used in silicone production, the silicon is ground into a fine powder to increase the surface area available for reactions read less
