Products Description

Silicon (Si) is a light chemical element that combines with oxygen and other elements to form silicates. Silicon in the form of silicates constitutes more than 25% of the Earth's crust. Silica (SiO₂) as quartz or quartzite is used to produce silicon ferroalloys and silicon metal. Demand for silicon ferroalloys is driven principally by the production of cast iron and steel. Silicon metal, which generally is produced like ferrosilicon in submerged-arc electric furnaces, is used not as a ferroalloy, but rather for alloying with aluminum and for production of chemicals, especially silicones. Small quantities of silicon are processed into high-purity silicon for use in the semiconductor industry.

High-purity silicon metal is used by many industries. In the chemical industry it is used for producing silicon compounds as well as silicon wafers used in photovoltaic solar cells and electronic semiconductors. And aluminum manufacturers use it to improve the already useful properties of aluminum. When used with aluminum, silicon improves its castability, hardness and strength.

Besides, aluminum demand has been growing steadily in recent years, as a reflection of the economic activity in both the developed and developing word. This demand of lighter and more economical material has triggered a growth in Silicon metal consumption by aluminum manufacturers.

That said, silicon compounds are the raw material for a large and growing number of industrial and consumer products such as:

Silicone rubber parts; Urethane foam; Sealants; Adhesives; Lubricants; Food additives; Coatings; Polishes and cosmetics; Aluminum; Polysilicon; Batteries; Advanced applications
