Abstract: In the system of 3Na2O·Al2O3·2SiO2·185H2O,in which water glass was taken as a sourse of SiO2, The changes in concentrations, of SiO2 and Al2O3 in the liquid phase of gel and amounts of the lower polysilicate anions with various polymerization degrees presented in the liquid and solid phases of gel during the crystallzation of zeolitse Awere investigated by the chemical analysis and the trimethylsilylation followed by gas ch-romatographic analysis (TMS-GC) respectively. The nucleation of zeolite Ain the liquid phase of gel was obseveed by electron microscope. According to these results, a mechanism of the formation of zeolite Awas proposed.
