The analysis of thermally stimulated current measurements by the use of the RMA method (Relaxation Map Analysis) shows that in a mordenite-type zeolite, sodium ions are localized into three different sites. It is assumed that each RMA peak results fr

The work presented here proposes a new interpretative method for thermally stimulated depolarization current (TSDC) measurements. By applying the concept of electronegativity equalization to TSDC results, we show that it is possible to obtain an expe

Calculations, confirmed by experimental evidence on a polymer and on two ionically conducting solids, show that the variation of thermally stimulated depolarization currents (TSDC) with the heating rate depends on the polarization decay function that

Thermally stimulated current (TSC) spectroscopy is widely used to understand dielectric relaxation in complex solid systems. However, when these systems contain free and bound charges, it appears that TSC spectra exhibit multicomponent signals, due b

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

We propose a new method for analyzing the experimental results obtained from thermally stimulated depolarization current experiments on ionic conductors. This method is based on a model developed to explain polarization in these materials. The fundam

The evolution of conduction and polarization phenomena is studied as a function of dehydration temperature (TT varying from 100 up to 400 °C) on a faujasite Y zeolite. The measurements are carried out as a function of frequency at different temperat
