Characteristics
Silicon Metal is a very important industrial product can be used in steel-making, cast iron, aluminum (aviation, aircraft & automobile parts production), and silicon optoelectronic device and many other industries. Metal silicon is made from quartz and coke in electric heating furnace smelting products. The main ingredient of silicon content is about 98%. The rest of impurities is iron, aluminum and calcium etc.
Application of Silicon Metal
1.Aluminum alloy ingot production, as additive of silicon content.
2.Dioxidizer in steelmaking as replacement of ferrosilicon.
3.As raw materials to produce poly-crystalline silicon.
