Silicate - Wikipedia
网页A silicate is any member of a family of polyatomic anions consisting of silicon and oxygen, usually with the general formula [SiO(4-2x)−. 4−x] n, where 0 ≤ x < 2. The family includes orthosilicate SiO4− 4 (x = 0), metasilicate SiO2− 3 (x = …
Silicate mineral - Wikipedia
网页A silicate mineral is generally an inorganic compound consisting of subunits with the formula [SiO 2+n] 2n−. Although depicted as such, the description of silicates as anions is a simplification. Balancing the charges of the silicate anions are metal cations, M x+. Typical cations are Mg 2+, Fe 2+, and Na +.

网页2024年8月25日 · The silicates, owing to their abundance on Earth, constitute the most important mineral class. Approximately 25 percent of all known minerals and 40 percent of the most common ones are silicates; the igneous rocks that make up more than 90 percent of Earth’s crust are composed of virtually all silicates.
Silicates
网页Silicates are the minerals containing silicon and oxygen in tetrahedral SiO 4 4-units, which are linked together in several patterns. About 95% of the earth’s crust is composed of silicate minerals, aluminosilicate clays or silica.
Silicate mineral | Definition & Types | Britannica
网页Silicate mineral, any of a group of silicon-oxygen compounds that are widely distributed throughout much of the solar system. The silicates make up about 95 percent of Earth’s crust and upper mantle, occurring as the major constituents of most igneous rocks.
