Rarely occurring cases are considered when zeolites, during the gradual increase in temperature and bypassing the amorphization stage, recrystallize into densely packed framework phases. Examples of transformations include: gismondine → anorthite, laumontite-wairakite, low-silica Na- and Ca-chabazites → phases with a sodalite framework. It is shown that these transformations occur due to the inversion of the vertices of part of the framework tetrahedra to the opposite side, i.e., through the "swing transfer" mechanism, which determines the presence of common structural elements in the original and newly formed phases. The role of the stoichiometric factor and the presence of wa-ter molecules in the frameworks at the moment of recrystallization is examined. Based on the devel-oped concepts, the possibility of recrystallization of the Na, Ca form of synthetic zeolite type P (Si/Al=1.8) into a feldspar phase of the andesine type is predicted and experimentally confirmed.
