The number of electrons present on the oil drop which has the static electric charge of Aluminosilicates either do not react with water, or do so too slowly. However, provided these materials have a high amorphous content when they are placed in an alkaline medium, they will hydrolyse and condense, forming new inorganic polymers that can develop load-bearing capacity.

Based on these basic structural units, we can construct a general structural chemical formula for the silicates. But one substitution in particular tends to mess things up a bit.

When two SiO 4 4-units are linked together, they form the pyrosilicate group, Si 2 O 7 6-. For example, thortveitite, Sc 2 Si 2 O 7 is a pyrosilicate. Ring and chain silicates

Sodium pyrosilicate is the chemical compound Na 6 Si 2 O 7.It is one of the sodium silicates, specifically a pyrosilicate, formally a salt of the unstable pyrosilicic acid H 6 Si 2 O 7. Type of chemical compound; either an ionic compound that contains the pyrosilicate anion, or an organic compound with the hexavalent ≡-O-≡ group.

These silicates can be cleaved easily just like graphite. 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).
