===Zeolite formation and geopolymers polymerisation===
The nature of soluble silicates is relevant to understanding [[biomineralization]] and the synthesis of [[aluminosilicate]]s, such as the industrially important [[catalyst]]s called [[zeolite]]s.<ref name=knight>{{cite journal | last1 = Knight | first1 = Christopher T.

Geopolymers are [[amorphous]] aluminosilicates whose production requires less energy than that of ordinary [[Portland cement]]. So, [[geopolymer cement]]s could contribute to limiting the {{CO2|link=carbon dioxide}} emissions in the Earth [[atmosphere]] and the [[global warming]] caused by this [[greenhouse gas]].
