Silicon Metal Description
Silicon is a lightweight element that combines with oxygen and other elements to form silicates. Silicates make up more than a quarter of the earth's crust. Silica (SiO₂) is used to produce metallic silicon and ferroalloys. The demand for silicon ferroalloys is driven by the production of cast iron and steel. Metallic silicon is produced in electric furnaces and is used to produce chemicals, especially silicones. A small amount of silicon produces high-purity silicon for use in the semiconductor industry.
High-purity metal silicon 2202 is used in many industries. In the chemical industry, it is used to produce silicon compounds and silicon wafers used in solar cells and semiconductors. Aluminum manufacturers use it to improve the properties of aluminum. When silicon is used with aluminum, it becomes easier to cast, harder, and stronger.
