Abstract

An attempt has been made to treat oscillatory dynamic phenomena in zeolites on the base of participating the cluster species of the peculiar thermodynamic characteristics in direct and reverse processes. These characteristics are defined by the fact that the bulk phase exceeds any cluster phase of the same substance in high temperature region for the chemical potential value by ?? causing the oscillatory dynamic phenomena in zeolite systems due to fusion of clusters into the bulk phase and bulk phase dissociation to clusters, repeated cluster fusion and so on. ?? value is shown to be a driving force of both direct and reverse processes.
