摘要
The purpose of the present work is to compare data obtained by impedance spectroscopy in several laboratories on the same ionically conductive materials. Yttria-doped zirconia, stabilized under the cubic form, was selected. Measurements were done in the temperature range 200-600 degrees C to get the bulk and the grain boundary contributions to the material impedance. The data were analyzed centrally. The de conductivity could be obtained with a fair accuracy. Problems concerning the determination of ac properties are clearly pointed out. Some recommendations are made to improve the general reliability of measurements made with the aid of impedance spectroscopy.
