Abstract

Electrical resistance measurements of NaI-AgI solid electrolyte showed that adding NaI to AgI stabilizes the transition from conducting ionic phase (β-AgI) to the superionic (α-AgI) at 420 K with increasing temperature. The ionic conductivity at the β → α transition of AgI increases by several orders of magnitude. Considering a phenomenological model based on a free energy density was fitted the abrupt jump of ionic conductivity. In this model, the equilibrium defect concentration (, R is the resistance) is the order parameter. Better results are achieved for the order parameter.
