The evolution of thermally stimulated depolarization current
(TSDC) measured on a mordenite Na zeolite is
examined as a function of the Na+ exchange degree.
According to this investigation, the dipolar
reorientation
is due to Na+, and the TSDC signal analysis leads to an
assessment of the interaction energies between the
hopping Na+ ions and the zeolitic lattice. The
values of these energies are found to be between 0.7 and
0.9
eV. According to the Na+ exchange degree and the
nature of the occupied Na+ sites, a quantitative
and
qualitative characterization of each site is given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
