Impedance of the Ag|Nd0.95Sr0.05F2.95 Crystal|Ag System

Electrochemical studies of the Ag|Nd_0.95Sr_0.05F_2.95 crystal|Ag system at 94 to 1072 K are carried out using impedance measurements over the 10⁻¹ to 10⁷ Hz frequency range. Contributions of conduction and bulk and electrode polarization are distinguished in the impedance spectra of the Ag| Nd_0.95Sr_0.05F_2.95|Ag cell. Anionic conductivity of the Nd_0.95Sr_0.05F_2.95 crystal varies from 3 × 10⁻¹³ to 0.4 S/cm. The mechanism of anionic conduction and models for the electrode and bulk polarization are discussed.__________Translated from Elektrokhimiya, Vol. 41, No. 8, 2005, pp. 1005–1009.Original Russian Text Copyright © 2005 by Sorokin.
