WebIsolated orthosilicate anions have the formula SiO4− 4. A common mineral in this group is olivine ( (Mg,Fe)2SiO4 ). Two or more silicon atoms can share oxygen atoms in various ways, to form more complex anions, such as pyrosilicate Si 2O6− 7 .

Orthosilicate Definition & Meaning - Merriam-Webster
WebMar 20, 2024 · Introduction As an alternative cathode, lithium iron orthosilicate (Li 2 FeSiO 4) has attracted considerable attention because of its low cost, high thermal stability, good safety, and environmental friendliness [ 1 ]. However, two important factors significantly influence its electrochemical performance. In chemistry, orthosilicate is the anion SiO 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. Orthosilicate salts, like sodium orthosilicate, are stable, and occur widely in nature as silicate minerals, being the defining feature of the nesosilicates. … See more The orthosilicate ion or group has tetrahedral shape, with one silicon atom surrounded by four oxygen atoms. In the anion, each oxygen carries a unit negative charge. The Si–O bond is 162 pm long. See more Europium doped barium orthosilicate (Ba2SiO4) is a common phosphor used in green light-emitting diodes (LEDs). Phosphor for blue LEDs can be made with strontium doped barium orthosilicate. Barium orthosilicate is a major cause of cathode poisoning See more Although very important in inorganic chemistry and geochemistry, the orthosilicate ion is rarely seen in organic chemistry. Two silicate compounds, however, are used in organic synthesis: tetraethyl orthosilicate or TEOS is used to link polymers, and is … See more In all silicates, silicon atom occupies the center of an idealized tetrahedron whose corners are four oxygen atoms, connected to it by single covalent bonds according to the octet rule. The oxygen atoms, which bears some negative charge, link to other cations (M ). This Si-O-M-O-Si linkage is strong and rigid, which properties are manifested in the rock-like silicates. The silicates can be … phenoleptil fass
