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

A large amount of silicon is used for smelting into ferrosilicon alloy as an alloying element in the iron and steel industry, and as a reducing agent in the smelting of many kinds of metals. Silicon is also a good component in aluminum alloys, and most cast aluminum alloys contain silicon. Silicon is the raw material of ultra-pure silicon in the electronics industry. Electronic devices made of ultra-pure semiconductor single crystal silicon have the advantages of small size, light weight, good reliability and long life. High-power transistors, rectifiers and solar cells made of silicon single crystals doped with specific trace impurities are better than those made of germanium single crystals. The research of amorphous silicon solar cells has progressed rapidly, and the conversion rate has reached more than 8%. Silicon molybdenum rod electric heating element can be used at a temperature of up to 1700 ° C, with resistance not easy to age and good anti-oxidation performance. Trichlorosilane, produced from silicon, can be formulated with hundreds of silicone lubricants and waterproofing compounds.
