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.
