Positron Annihilation Lifetime Spectroscopy Application in Structural Investigation of Low-silica Zeolites and their Amorphous Precursors

In this work a short review of recently obtained results is shown. Positron annihilation lifetime spectroscopy has been efficiently used for investigation of the zeolite precursors structure influenced by presence of different alkali cations. Also, stages of zeolite A crystallization and the effect of dehydration of low-silica zeolites on the free volume of structural cages in correlation to the number and atomic sizes of non-framework cations present have been monitored.
