Abstract
Microporous framework aluminosilicates with the cancrinite- and sodalite-type structures containing NO −3 , CO 2−3 , SO 2−4 and PO 3−4 , as extra-framework anions were synthesized under hydrothermal conditions at temperatures from 160 to 200°C. SO 2−4 exhibits the highest affinity to cancrinite structure at the competition of various X anions. Chemical composition, X-ray diffractometry characteristics, and IR spectra of the compounds obtained, as well as kinetics and mechanism of thermal transformations of nitrate counterpart of cancrinite, were studied.
