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]
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). The name is also used for any salt of such anions, such as sodium metasilicate; or any ester containing the corresponding chemical group, such as tetramethyl orthosilicate. [1]
Sodium orthosilicate is the chemical compound with the molecular formula Na 4 SiO 4. It is one of the sodium silicates, specifically an orthosilicate, formally a salt of the unstable orthosilicic acid H 4 SiO 4. [2] [3] [4]
x · (SiO 2) y, such as sodium metasilicate (Na 2 SiO 3), sodium orthosilicate (Na 4 SiO 4), and sodium pyrosilicate (Na 6 Si 2 O 7). The anions are often polymeric. These compounds are generally colorless transparent solids or white powders, and soluble in water in various amounts.
Nesosilicates (from Greek νῆσος nēsos 'island'), or orthosilicates, have the orthosilicate ion, present as isolated (insular) [SiO 4] 4− tetrahedrums connected only by interstitial cations. The Nickel–Strunz classification is 09.A –examples include:
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. Silicic acids play important roles in biomineralization and technology. [2] [3] [4] It is the parent acid of the orthosilicate anion SiO 4− 4.

Unit cell of Ca 2 SiO 4. Color code: red (O), blue (Ca), gold (Si). As verified by X-ray crystallography, calcium silicate is a dense solid consisting of tetrahedral orthosilicate (SiO 4 4-) units linked to Ca 2+ via Si-O-Ca bridges. There are two calcium sites. One is seven coordinate and the other is eight coordinate. [11]
