The layers are held together by weak van der Waal's forces. 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). Pyrosilicates are silicates which contain Si2O76-. They are formed by joining two tetrahedral Si2O44-.

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 Sorosilicates. Mineral. Formula.

… Pyrosilicate sodium pyrosilicate Na 6Si 2O 7, a possible component of water glass. sodium iron (II) pyrosilicate Na 2Fe 2Si 2O 7, a potential cathode material for batteries. sodium manganese (II) pyrosilicate Na 2Mn 2Si 2O 7, another potential cathode material. Sodium pyrosilicate is the chemical compound Na 6Si 2O 7. A pyrosilicate is a chemical compound that contains the phyllosilicate anion Si2O6-7 with the hexavalent group −(O3Si-O-SiO3)− .

Pyrosilicates are silicates which contain Si2O76-. They are formed by joining two tetrahedral Si2O44-. When two Si2O44- are joined, there is removal of one oxygen atom and the two units join at the corner oxygen atom. Example is thortveitite, Sc2Si2O7.
