For powders of oxide-ion conductors based on Al/Fe-doped lanthanum silicates as well as Sc+Ce-doped zirconia, the temperature–programmed exchange with C18O2 in the SSITKA mode was applied for estimation of the oxygen self-diffusion coefﬁcients Do. Comparison with results obtained for dense ceramics of these electrolytes using SIMS isotope proﬁling and conductivity measurements demonstrated a reasonable agreement for powders sintered at high temperatures, thus providing required veriﬁcation of C18O2 SSITKA approach. For powders calcined at moderate temperatures much lower values of D O were obtained thus suggesting a strong negative effect of inhomogeneity of dopants spatial distribution on the oxygen mobility.
