Briefintroduction：
Silicon in the form of a crystalline solid in blue-grey metallic color is rarely found naturally. It is rather can be found in planets, meteorites and dusts in silicon dioxide forms. Silicon is a second most abundant element that can be found in the Earth's crust, followed by oxygen. When in its elementary form, its crystal structure is similar to that of diamond. This utility element can form semi-conducting crystals for several applications. This semi-conductive metal is useful in manufacturing steel, microchips and solar cells.
Features and usage：
* As raw materials to produce poly-crystalline silicon.
* Aluminum alloy ingot production, as additive of silicon content.
* Dioxidizer in steelmaking as replacement of ferrosilicon.
