Silicon processing: from quartz to crystalline silicon ...

2011-3-15  temperature, silicon dioxide is reduced to molten silicon. The furnaces are operated such that there is a layer of solid material (outer reaction zone) on top of the molten bath (inner reaction zone) to maximize the silicon yield. The silicon is tapped from the furnace through a tap-hole at the bottom, and refined by slag treatment or gas purging.

How Is Silicon Obtained? eHow

2017-8-30  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
