Silicon metal441, also known as crystalline silicon or industrial silicon, is mainly used as the additive of non-ferro-alloys. Silicon metal is a product made of quartz and coke in the electric heating furnace. The content of the main component silicon is around 98% (in recent years, 99.99% of the Si content is also included in the silicon metal).
Silicon441 is widely used in smelting ferro-silicon 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 alloys, most of the cast aluminum alloys contain silicon.Silicon is the raw material of ultra-pure silicon in electronic industry. The electronic devices made of ultra-pure semiconductor monocrystalline silicon have the advantages of small size, light weight, good reliability and long life.
Widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance.
