DESCRIPTION
ZhenAn Silicon metal is primarily used as an additive in non – iron – based alloys. Silicon metal is produced by smelting quartz and coke in the electric furnace. The content of the main component silicon element is about 98% (in recent years, 99.99% of the content of Sl is also included in silicon metal), and the remaining impurities are iron, aluminum, calcium, etc. Silicon is widely used in smelting ferrosilicon alloy as alloying element in iron and steel industry and as reducing agent in many kinds of metal smelting. Silicon is also a good component of aluminum alloy, the vast majority of cast aluminum alloys contain silicon. Silicon is the raw material of ultra-pure silicon in the electronics industry. The electronic devices of ultra-pure semiconductor monocrystalline silicon have the advantages of small size, light weight and long life.
