Abstract

We have measured the electric modulus M(t) of the ionic conductor 0.4 Ca(NO3)2-0.6 KNO3 (CKN) by recording the electric field relaxation E(t) under the constraints of a constant displacement D0. The vitreous material CKN is studied in its glassy state for temperatures 240 K≤ T≤330 K and for times 7 × 10-3 s≤t≤3 × 105 s. In this range the dc conductivity varies from 3 × 10-11 to 5 × 10-17 S/cm according to Arrhenius behavior. We show that the time dependent resistivity p(t), instead of the conductivity σ(t), is an appropriate quantity for assessing the time dependent and steady state effects of ionic diffusivity on the basis of experimental modulus data M/(t) recorded in the time domain. Even substantial electrode polarization is not critical with regard to this data analysis.
