The agreement between the experimental data and the equation achieved using the assumption of cation-hopping conduction [114] testify that this hypothesis is in concordance with the experimental data. It is interesting to recognize the difference between the measured apparent activation energies for sodium and calcium zeolites (see Table 4.10 [114]). As was hitherto observed for the polarization phenomena, Na+ cations are more mobile than Ca2+ cations this effect also explains the observed differences in the measured apparent activation energies for cationic conduction for Na+ and Ca2+.
