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 | 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.
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.

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.

WEBJun 30, 2023 · Silicates is based on the basic chemical unit SiO 44-, tetrahedron shaped anionic group. The central silicon ion has a charge of positive four while each oxygen has a charge of negative two (-2) and thus each silicon-oxygen bond is equal to one half (½ ) the total bond energy of oxygen.
