Idealized structure of sodium metasilicate.

Metasilicates are silicates containing ions of empirical formula Template:Chem. Common stoichiometries include MTemplate:SuSiO₃ and M^IISiO₃. Metasilicates can be cyclic, usually the hexamer Template:Chem2 or chains Template:Chem2.

Common compounds containing metasilicate anion are:

• Inosilicates
• Metasilicic acid (hydrogen metasilicate)
• Sodium metasilicate
• Calcium metasilicate
