Silicon Metal
Structural characteristics and application:
Silicon metal, also known as crystalline silicon or industrial silicon, is used primarily as an additive to non-iron based alloys. Silicon metal is a product smelted from quartz and coke in an electrically heated furnace, with the main component, elemental silicon, containing around 98% (in recent years, those containing 99.99% Si have also been included in silicon metal) and the remaining impurities being iron, aluminium, calcium, etc.
Application:
1.Aluminum alloy Production
2.Solar industry and electronics industry.
3.Silicone rubber production
4.Make high purity semiconductors
5.Production of silicone resin and silicone oil
