摘要
Stabilization of the cubic perovskite phase was demonstrated in the SrCo0.90-xFe0.10CrxO3-delta oxide system at x greater than or equal to 0.03. Oxygen permeability of SrCo(Fe, Cr)O3-delta solid solutions was independent of chromium content at x = 0.01-0.05. It was found that reducing ceramic grain size dimensions resulted in decreasing thermal expansion electrical conductivity, and oxygen permeability of SrCo(Fe, Cu)O3-delta ceramic membranes. Oxygen transport through SrCo(Fe, M)O3-delta ceramics was shown to be limited by both the bulk ionic conductivity and oxygen exchange currents. The limiting effect of the membrane permeate-side surface on the permeation was higher in comparison with that on the feed-side surface.
