Metallic Silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. The silicon metal is smelted by quartz and coke in the electric heating furnace, the content of the main component silicon is about 98% (in recent years, 99.99% of the SI content is also included in the silicon metal) , the other impurities are iron, aluminum, calcium and so on.
The classification of metallic silicon is usually based on the content of iron, aluminum and calcium. According to the content of Fe, AL and CA in silicon metal, silicon metal can be divided into 553,441,411,421,3303,3305,2202,2502,1501,1101 and so on.
