Silicate - Wikipedia
WEBIn chemistry, 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
WEBSilicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of Earth's crust. [1] [2] [3] In mineralogy, silica (silicon dioxide, SiO2) is usually considered a silicate mineral rather than an oxide mineral.
Silicate mineral | Definition & Types | Britannica
WEBSilicate 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.
Mineral - Silicates, Crystalline, Structure | Britannica
WEBApproximately 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 - New World Encyclopedia
WEBIn chemistry, a silicate is a compound containing an anion in which one or more central silicon atoms are surrounded by electronegative ligands. Most often, the ligands are oxygen atoms (to produce anions such as [SiO 4 ] 4− ), but in some cases, the ligands are fluorine atoms (to produce anions such as hexafluorosilicate, [SiF 6 ] 2− ).
