Nonlinear impedance in oxide glasses containing single and mixed alkali ions

Abstract

The aim of the present was to find more clues on the nonlinearities in impedance of oxide glasses. The first family of researched glasses has a composition of FeO-P2O5-Na2O. Oxide glasses containing iron and alkali are well known for a very low alkali ion mobility and may be considered purely polaron conducting. These glasses show no detectable nonlinearities in the impedance spectra. The second was a family of ionic conducting SiO2-Na2O-Al2O3 glasses. The contents of the third harmonics at certain cases reach values of about 10% at higher temperatures and extremely low frequency region. It has been pointed out that such a nonlinearity may imply errors in interpretation of conventional linear impedance measurements.
