Abstract
A comaprison between different ac measuring techniques has been performed and evaluation methods for the determination of ionic conductivity in oxygen ion conductors are described. 2- and 4-point impedance measurements using two different frequency response analysers (Solartron FRA-1174 and FRA-1250) are compared.
The materials studied were polycrystalline cubic ceriagadolinia, tetragonal zirconia-yttria ceramics and single crystallin YSZ. Empirical rules for the determination of conductivity by geometrical methods from “overlapping” semicircies in the complex plane representation of the immittance data were established.
This was supported by model calculations and non-linear least squares fitting techniques.
