Silicon Metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Silicon Metal is a product produced by smelting quartz and coke in an electric furnace. The content of silicon element, the main component, is about 98% (in recent years, 99.99% of Si is also included in Silicon Metal), and the rest impurities are iron, aluminum, calcium, etc.

Silicon is widely used in smelting ferrosilicon alloy as alloy element in iron and steel industry and as reducing agent in smelting many kinds of metals. Silicon is also a good component in aluminum alloys. Most cast aluminum alloys contain silicon. Silicon is the raw material of ultra pure silicon in electronic industry. Electronic devices made of ultra pure semiconductor monocrystalline silicon have the advantages of small volume, light weight, good reliability and long service life. High power transistors, rectifiers and solar cells made of silicon single crystal doped with specific trace impurities are better than those made of germanium single crystal. The research of amorphous silicon solar cells has made rapid progress, and the conversion rate has reached more than 8%.
Industrial silicon can be used in aluminum factories, ceramics and other industries. High purity monocrystalline silicon is an important semiconductor material.
