One of the most fundamental basis of the hydrothermal synthesis of zeolites is the mineralizing role of water, which is greatly cissisted by the free OH concentration in the solution / hydrogel. Apart from this basic requirement of mineralizability, other factors like. Si / A1 molar ratio, pH of the gel, aging at lower temperature, crystallization temperature and time etc., influence the type and quality of the crystalline material in rather specific ways [1]. It is clear that the enhancement of the crystallisation rate is not much dependent of the choice of counter cation (H, Na or K) of a particular oxyanion promoter, at least for high silica... [Pg.228]

Examples of polysiloxane degradation studies include the role of surfactants in suppressing aging of silica-PDMS gels, " the effects of pigments on the stability of montmorillonite-PDMS composites, and the use of NMR and mass spectrometry to characterize degradation processes. " " ... [Pg.98]
