  • 11. History Of Silicon In 1800, Davy thought silica to be a compound and not an element; but in 1811, Gay Lussac and Thenard probably prepared impure amorphous silicon by heating potassium with silicon tetrafluoride. In 1824 Berzelius, genera%y credited with the discovery, prepared amorphous silicon by the same general method and purified the product by removing the fluosilicates by repeated washings.
  • 12. How is Silicon Purified? Today, silicon is purified by converting it to a silicon compound that can be more easily purified by disti%ation than in its original state, and then converting that silicon compound back into pure silicon. Trichlorosilane is the silicon compound most commonly used as the intermediate, although silicon tetrachloride and silane are also used.
  • 13. Where is Silicon found? Pure silicon cannot be found in nature, though it makes up approximately 25.3-28.0% of the earth's crust, making it second in abundance (oxygen is first). Silicon is obtained by heating silica, or silicon dioxide with carbon or magnesium (or some reducing agent) in an electric furnace.
