摘要: Abstract Attenuated—total—reflection infrared spectroscopy has been applied to characterize tetramethylammonium double-four-ring silicates in solution as well hydrate crystals. It is shown that silicate solutions at elevated temperatures (up 85°C) still contain significant concentrations of anions. Furthermore, the temperature-dependent shift equilibrium between anions appears be fully reversible. A relation role zeolite syntheses suggested.
