A silicate is a compound containing an anionic silicon compound. The great majority of the silicates are oxides, but hexafluorosilicate ([SiF6]2â) and other anions are also included. 4 or its compounds. Related to orthosilicate are families of anions (and their compounds) with the formula [SiO2+n]2nâ.
The basic building block of all silicate minerals is the [SiO4] 4â tetrahedron. Silicate minerals containing chains are termed inosilicates. In single chains (SiO 3 2â) n, the silicon to oxygen ratio is 1:3, while in double chains (Si 4 O 11 6â) n, the silicon to oxygen ratio is 4:11. The formula of silicate sheet is (Si 2 O 5 2â) n. Silicate minerals containing sheets are termed phyllosilicates. Key Terms
