Calcium aluminosilicate, an aluminosilicate compound with calcium cations, most typically has the chemical formula, CaAl 2 Si 2 O 8. As a food additive, it is sometimes designated “E556”. In minerals, as in feldspar, it can be found as anorthite, an end-member of the plagioclase series.

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 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.

Synonyms. disilicate (6-) Disilikat.

Sorosilicate, formerly called pyrosilicate, any member of a group of compounds with structures that have two silicate tetrahedrons (each consisting of a central silicon atom surrounded by four oxygen atoms at the corners of a tetrahedron) linked together. Because one oxygen atom is shared by two tetrahedrons, the chemical formula contains Si 2 O 7, as in melilite or hemimorphite.

More In chemistry, a silicate is any member of a family of anions consisting of silicon and oxygen, usually with the general formula [SiO− 4−x] n, where 0 ≤ x < 2.

Structural principles Modeling as corner-sharing tetrahedra. In most commonly encountered silicates, including almost all silicate minerals, each 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. Sodium pyrosilicate is the chemical compound Na 6 Si 2 O 7.It is one of the sodium silicates, specifically a pyrosilicate, formally a salt of the unstable pyrosilicic acid H 6 Si 2 O 7.

The formula of silicate sheet is (Si2O52−)n. Silicate minerals containing sheets are termed phyllosilicates. Sodium metasilicate is the chemical substance with formula Na 2SiO 3, which is the main component of commercial sodium silicate solutions. It is an ionic compound consisting of sodium cations Na+ and the polymeric metasilicate anions [–SiO2− 3–]n.

In chemistry, a silicate is any member of a family of 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, n = 2).The name is also used for any salt of such anions, such as sodium metasilicate; or any

disilicate Si2O76-. More Because one oxygen atom is shared by two tetrahedrons, the chemical formula contains Si 2 O 7, as in melilite or hemimorphite. The structure of pyrosilicate is: The reds are oxygen atoms and greens are silicon. Cyclic silicates contains (SiO 3) n 2n-which are formed by linking three or more tetrahedral SiO 4 4-units cyclically.
