In chemistry, orthosilicate is the anion SiO 4− 4, or any of its salts and esters. It is one of the silicate anions. It is occasionally called the silicon tetroxide anion or group. [1] Orthosilicate salts, like sodium orthosilicate, are stable, and occur widely in nature as silicate minerals, being the defining feature of the nesosilicates. [2]
Structure of the orthosilicate anion SiO 4− 4. 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 ...
Orthosilicic acid (/ ˌ ɔːr θ ə s ɪ ˈ l ɪ s ɪ k /) is an inorganic compound with the formula Si(O H) 4.Although rarely observed, it is the key compound of silica and silicates and the precursor to other silicic acids [H 2x SiO x+2] n.
Carbon–silicon bonds are absent in biology, however enzymes have been used to artificially create carbon-silicon bonds in living microbes. [8] [9] [10] Silicates, on the other hand, have known existence in diatoms. [11] Silafluofen is an organosilicon compound that functions as a pyrethroid insecticide. Several organosilicon compounds have ...
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.
Sodium silicate is a generic name for chemical compounds with the formula Na 2x Si y O 2y+x or (Na 2 O) x · (SiO 2) y, such as sodium metasilicate (Na 2 SiO 3), sodium orthosilicate (Na 4 SiO
Aluminum silicate (or aluminium silicate) is a name commonly applied to chemical compounds which are derived from aluminium oxide, Al 2 O 3 and silicon dioxide, SiO 2 which may be anhydrous or hydrated, naturally occurring as minerals or synthetic.
Sodium orthosilicate is the chemical compound with the molecular formula Na 4 SiO 4. It is one of the sodium silicates, specifically an orthosilicate, ...
