Abstract
29Si-MAS NMR spectroscopy has been proved to be a versatile tool to follow the reaction development from the signal ratio of the initial material and the crystallization product, if the spectra of both compounds could be clearly distinguished in each sample. On this basis the hydrothermal transformation of kaolinite into nitrite-sodah'te Na8[AlSiO4]6(NO)2 has been investigated at a temperature of 353 K. The crystallization process was followed in the mid-stage of crystal growth for times from 6 to 24 h. The role of carbonate impurities as well as the influence of the time of nitrite-salt addition to the reaction mixture have also been included in this experimental study.
