equipment for producing silicon

equipment for producing silicon

The first step in producing silicon suitable for solar cells is the conversion of high-purity silica sand to silicon via the reaction SiO 2 + 2 C → Si + 2 CO, which takes place in a furnace at temperatures above 1900°C, the carbon being supplied usually in the form of coke and the mixture kept rich in SiO 2 to help suppress formation of SiC. Further chemistry is undertaken to fully eliminate SiC from the product
