How Is Silicon Obtained? | eHow

2 天前 · The Production of Pure Silicon. Pure silicon is produced by heating silicon dioxide along with carbon in an arc furnace at around 1900 degrees Celsius. The heat causes the oxygen in the silicon dioxide to split from the silicon and bond with the carbon. Hence, the outputs of this process are pure silicon, carbon monoxide and carbon dioxide.
