Study of the influence of the silica source on the properties of silicate solutions and particulate properties of zeolite X
It has been shown previously that zeolite synthesis results can be influenced by the silica source used. It also has been reported by several research groups recently that nanometer sized particulates were observed in the synthesis medium prior to the onset of zeolite crystallization. It has been conjectured that they may play a role in zeolite synthesis. In this study the distinguishing features of four different silica sources were characterized by NMR, the molybdate method, synthesis results, and preliminary evaluation of quasi-elastic light scattering spectra. The results suggest that differences in the silicate solutions stem from the presence of species larger than those detected by 29Si-NMR methods, and that changes in some silicate solutions occur during room temperature aging, prior to mixing with the aluminate solution.
