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 simplest silicate structure, that of the mineral olivine , is composed of isolated tetrahedra bonded to iron and/or magnesium ions. In olivine, the −4 charge of

Silicate anions are often large polymeric Because one oxygen atom is shared by two tetrahedrons, the chemical formula contains Si 2 O 7, as in melilite or hemimorphite.

Sodium silicate is a generic name for chemical compounds with the formula Na 2xSi yO 2y+x or x· y, such as sodium metasilicate Na 2SiO 3, sodium orthosilicate Na 4SiO 4, and sodium pyrosilicate Na 6Si 2O 7.

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. Type of chemical compound; either an ionic compound that contains the pyrosilicate anion, or an organic compound with the hexavalent ≡-O-≡ group. SiO2Silicon dioxide/Formula. Which is Pyrosilicate?
