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.
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
Tetraethyl orthosilicate, formally named tetraethoxysilane (TEOS), ethyl silicate is the organic chemical compound with the formula Si(OC 2 H 5) 4. TEOS is a colorless liquid. It degrades in water. TEOS is the ethyl ester of orthosilicic acid, Si(OH) 4. It is the most prevalent alkoxide of silicon. TEOS is a tetrahedral molecule.
Organosilicon chemistry is the study of organometallic compounds containing carbon–silicon bonds, to which they are called organosilicon compounds. Most organosilicon compounds are similar to the ordinary organic compounds, being colourless, flammable, hydrophobic, and stable to air.
Sodium orthosilicate is the chemical compound with the molecular formula Na 4 SiO 4. It is one of the sodium silicates, specifically an orthosilicate, ...
Calcium silicates are produced by treating calcium oxide and silica in various ratios. Their formation is relevant to Portland cement. [5]Calcium silicate is a byproduct of the Pidgeon process, a major route to magnesium metal.
