“…An extensive study has been proposed on the latter (Badot et al, 1987) on microcrystalline solids in a wide frequency domain. The ion dynamics of superionic conductors provides an opportunity to study the influence of the porosity of samples on the complex permittivity at frequencies >106 Hz (Colomban et al, 1992).…”

A B S T RA C T:From measurements of dielectric losses as a function of frequency and temperature, as well as thermally stimulated depolarization currents, performed on a dry Na-montmorillonite, a qualitative description of the conduction mechanism has been proposed for this type of material. A representative approach related to the polarization phenomenon determined on this material led to the evaluation of the elementary energy Wj, connected with the reorientation of the dipoles during the hopping process. The results show the coherence between the polarization conductivity and the thermally stimulated currents methods.

On the basis of dilatometric and dielectric investigations of NH(CH3)3CuCl3 · 2H2O crystals the earlier unknown phase transition with considerable temperature hysteresis was found at T c 1 = 198 K and T h 1 = 223 K, respectively, in cooling and heating runs. Existence of the characteristic dielectric dispersion was revealed within the high-temperature phase. It corresponds to the single dielectric relaxator below 250 K as well as to co-existence of two relaxators above this temperature. The determined values of the activation energy and relaxation time are characteristic of the co-operative reorientation of the trimethylammonium cation (high-frequency relaxator) whereas the combined reorientation motions of the CuCl 2 · 2H 2 O chains would be responsible for the low-frequency relaxation process. It was found that the above mentioned quasi-Debye type processes are involved into the mechanisms of the protonic conductivity.
