Discovered in 1824 by Jons Jacob Berzelius in Stockholm, Sweden.  The name is derived from "silicus", the Latin word for flint.

• Pure form used to manufacture computer chips.  Can also be doped with other elements for transistor, solar cell, and rectifier applications.
• Silica used in glass industry.  Also used to make concrete and cement.
• Silicones used as lubricants and sealants.
• Silicon Carbides used in abrasive applications.
• Used in steel making as an important deoxidizer.  Can be used to improve tensile strength, hardenability, and corrosion resistance.  Adverse effects include impaired hot/cold workability and machinability.  Can also degrade surface quality in low Carbon steels.  
• Used in high temperature steels due to enhanced resistance to scaling.
