With two shared oxides bound to each silicon, cyclic or polymeric structures can result. The cyclic metasilicate ring Si 6 O 12− 18 is a hexamer of SiO 3 2-. Polymeric silicate anions of can exist also as long chains. In single-chain silicates, which are a type of inosilicate, tetrahedra link to form a chain by sharing two oxygen atoms each.
Calcium silicate (CaSiO 3), a commonly used anti-caking agent, added to e.g. table salt, absorbs both water and oil. Anticaking agents are also used in non-food items such as road salt , [ 3 ] fertilisers , [ 4 ] cosmetics , [ 5 ] [ 6 ] and detergents .
Sodium orthosilicate has been considered as an interfacial tension reducing additive in the waterflooding of oil fields for enhanced oil extraction. In laboratory settings, it was found to be more effective than sodium hydroxide for some types of oil. [5]
Lithium aluminium silicate mineral spodumene. Silicate 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, SiO 2) is usually considered a silicate mineral rather than an ...
The oxide mineral class includes those minerals in which the oxide anion (O 2−) is bonded to one or more metal alloys. The hydroxide -bearing minerals are typically included in the oxide class. Minerals with complex anion groups such as the silicates , sulfates , carbonates and phosphates are classed separately.
It's a classic tale: You have last-minute guests coming over for dinner or a bake sale fundraiser you didn't find out about until the night before—and now you need to concoct some tasty treats ...

In chemistry, a silicic acid (/ s ɪ ˈ l ɪ s ɪ k /) is any chemical compound containing the element silicon attached to oxide (=O) and hydroxyl (−OH) groups, with the general formula [H 2x SiO x+2] n or, equivalently, [SiO x (OH) 4−2x] n. [1] [2] Orthosilicic acid is a representative example.
