History
In 1800, Sir Humphry Davy thought silica to be a compound and not an element; but in 1811, Gay Lussac and Louis Jacques Thénard probably prepared impure amorphous silicon by heating potassium with silicon tetrafluoride. In 1824 Jöns Jakob Berzelius prepared amorphous silicon by the same general method. Henri Deville in 1854 first prepared crystalline silicon, the second allotropic form of the element. From the Latin word silex, silicis, flint
| Discoverers | Jöns Berzelius |
|---|---|
| Discovery Location | Sweden |
| Discovery Year | 1824 |
| Etymology (Name Origin) | Latin: silex, silicus, (flint). |
| Pronunciation | SIL-i-ken (English) |
If breathed in as a fine silica/silicate dust, it may cause chronic respiratory problems
Silicon also has the unusual property that it expands as it freezes
Uses
In the form of sand and clay it is used to make concrete and brick; it is a useful refractory material for high-temperature work, and in the form of silicates it is used in making enamels, pottery, etc. Silica, as sand, is a principal ingredient of glass. Silicon chips are the basis of modern electronic and computing. Silicon carbide, more commonly called carborundum is used in abrasives. Used in glass as silicon dioxide (SiO2). Silicon carbide (SiC) is one of the hardest substances known and used in polishing. Also the crystalline form is used in semiconductors.
Sources
Makes up major portion of clay, granite, quartz (SiO2), and sand. Commercial production depends on a reaction between sand (SiO2) and carbon at a temperature of around 2200 °C.
