About 95 % of the eath's crust is composed of silicated minerals, aluminosilicate clays, or silica. The majority of silicate minerals are very insoluble, because they have an infinite ionic structure and because of the great strength of the Si - O bond. the basic structural units of silicate is (sIO_(4))^(4-) tetrahedra. The (SiO_(4))^(4-) tetrahedral may polymerize in to large units by sharing atoms Pyllo-silicates are formed by the sharing of the O atoms on...... corners of each tetrahedron with other tetrahedral

Silicates are metal derivatives of silicic acid. Silicates are formed by heating metal oxide or metal carbonate with sand. Na_(2)CO_(3) underset(SiO_(3)) overset("Fused with Sand")toNa_(4)SiO_(4),Na_(2)(SiO_(3)) etc A silicate in general has Si-O bond and possesses a complex network solid having silicate ion SiO_(4)^(4-) as the basic structural unit. These silicates occurs singly or by sharing oxygen atom is small occurs singly or by sharing oxygen atom is small groups, in cyclic groups, in infinite chains or infinite sheets giving different structures to silicates such as chain silicates, ring silicates, cyclic silicates, sheet silicates, three dimensional silicates etc., The general formula (SiO_(3)^(2-))_(n) forms
