Silicon processing: from quartz to crystalline silicon

2011-3-15  typical industrial silicon furnace has a shell diameter of about 10 m. Three pre-baked carbon electrodes, submerged into the charge materials, supply a three-phase current that heats the charge materials up to about 2 000oC. At this 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. During refining, inclusions are removed, and the composition is adjusted to the specified value. Subsequent to refining, the molten alloy is allowed to cool in a mould, and then crushed to a specific size. Metallurgical-grade silicon
