Abstract

The effect of scandium content in CaZr1–x Sc x O3–x/2 on electrical conductivity and oxygen exchange kinetics was investigated. The electrical conductivity was studied by means of impedance spectroscopy depending on temperature (700–850 °С) and oxygen partial pressure (2.1 · 104 > pO2 > 10–15 Pa). The oxygen exchange kinetics was studied using the isotope exchange method with gas phase equilibration in the temperature range of 700–850 °С and oxygen pressures of 0.13–6.7 kPa. The oxygen tracer diffusion coefficient, the oxygen heterogeneous exchange rate, and the electrical conductivity of oxides with the growing scandium content were found to increase. It was assumed that the electronic defects play an important role in the oxygen surface exchange.
