Smelting process of crystalline silicon
Metal silicon 98 is also called crystalline silicon or industrial silicon. The main component silicon content is about 98%. (In recent years, metal silicon also contains substances with Si content of 99.99%). Its main use is as an additive for non-ferrous base alloys. Metal silicon 98 is smelted by quartz and coke in an electric furnace. Other impurities are iron, aluminum, calcium, etc.
