Zeolite formation and geopolymers polymerisation

The nature of soluble silicates is relevant to understanding biomineralization and the synthesis of aluminosilicates, such as the industrially important catalysts called zeolites. Along with aluminate anions, soluble silicate anions also play a major role in the polymerization mechanism of geopolymers. Geopolymers are amorphous aluminosilicates whose production requires less energy than that of ordinary Portland cement. So, geopolymer cements could contribute to limiting the CO emissions in the Earth atmosphere and the global warming caused by this greenhouse gas.
