Pyrosilicate
Chemical compound / From Wikipedia, the free encyclopedia
A pyrosilicate is a type of chemical compound; either an ionic compound that contains the pyrosilicate anion Si
2O6−
7, or an organic compound with the hexavalent ≡O
3Si-O-SiO
3≡ group. The anion is also called disilicate[1] or diorthosilicate.

Ionic pyrosilicates can be considered salts of the unstable pyrosilicic acid, H
6Si
2O
7. Unlike the acid, the salts can be stable. Indeed, pyrosilicates occur widely in nature as a class of silicate minerals, specifically the sorosilicates.
Some notable synthetic pyrosilicates include
- 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.[2] - sodium manganese(II) pyrosilicate Na
