You might be surprised to learn that silicon is extracted from silica sand – that's right, sand! But in its natural form, silica has too much oxygen to be silicon so the material is mixed with carbon and heated in an electric furnace to a …

This is accomplished by heating a mixture of silica and carbon in an electric arc furnace to a temperature in excess of 2,000°C. The carbon reacts with the oxygen in the molten silica to produce carbon dioxide (a by-product) and silicon, which settles in …

The process of turning sand into silicon involves several steps: Purification. The sand is heated and combined with carbon to produce silicon and carbon dioxide. The silicon produced in this step still contains impurities. Refining. To create high-purity silicon, the crude silicon is further refined by a variety of processes.
