CharacteristicsCompositionCausesApplicationsOther usesUsesPropertiesSilicon (Si) is a semi-metallic or metalloid, because it has several of the metallic characteristics. Silicon is never found in its natural state, but rather in combination with oxygen as the silicate ion SiO44- in silica-rich rocks such as obsidian, granite, diorite, and sandstone. Feldspar and quartz are the most significant silicate minerals. Silicon alloys include a variety of metals, including iron, aluminum, copper, nickel, manganese and ferrochromium.

Silicon | Minerals Education Coalition

DescriptionBiological BenefitsSourcesNamed from the Latin word meaning “flint,” silicon is a shiny, blue-gray metallic substance. It looks like a metal, but its other characteristics are more non-metallic than metallic. It is the second-most common element in the Earth’s crust, mostly in the form of silica (SiO2). Pure silicon is never found in nature. Silicon, like its neighbor carbon, is a very useful element. It is used in metal alloys, especially with aluminum, steel, copper a在mineralseducationcoalition.org上查看更多信息
