What is Silicon used for?
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
- Food additives
- Polishes and cosmetics
