DESCRIPTION
In industry, silicon metal is usually made by carbon reduction of silicon dioxide in the electric furnace chemical reaction equation: SiO2 + 2C Si + 2CO so that the purity of silicon metal is 97~98%, called silicon metal and then melt it after recrystallization, with acid to remove impurities, the purity of silicon metal is 99.7~99.8%
