Silicate - Wikipedia
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 SiO 4− 4 (x = 0), metasilicate SiO 2− 3 (x = 1), and pyrosilicate Si 2 O 6− 7 (x = 0.5, n = 2).
Silicate mineral - Wikipedia
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 +. The Si-O-M linkage between the ...
Silicate - Definition, Structure, Classification, Examples, Uses and ...
Silicate - Silicates are the minerals containing silicon and oxygen in tetrahedral SiO44- units, which are linked together in several patterns. About 95% of the earth crust is composed of silicate mineral, aluminosilicate clays or silica.
Silicate mineral | Definition & Types | Britannica
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.

2024年12月7日 · 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. The fundamental unit in all silicate structures is the silicon-oxygen (SiO4)4– tetrahedron.
Silicate - an overview | ScienceDirect Topics
A silicate is a compound with anions consisting of silicon and oxygen. This family includes orthosilicate SiO 4 4 − (x = 0), metasilicate SiO 2 −. Silicate anions are commonly large polymeric molecules with a prolonged range of structures, comprising rings and chains.
Silicate - Simple English Wikipedia, the free encyclopedia
In chemistry, a silicate is a chemical compound consisting of one or more central silicon atoms that are surrounded by electronegative anions. The most common silicate species consist of silicon with oxygen as the anion.
