Phase separation-promoted ion conduction in SrFe0.67Ta0.33O3 (-) (delta) ceramics

The electrical conductivity of SSrFe0.67Ta0.33O3 (-) (delta) measured in the oxygen partial pressure range from 10-2 to 0.5 atm at 700-950 degrees C, exhibits an anomalous and reversible increase in moderately reducing atmospheres, substantially contributed by oxygen ion transport. The coulometric t...
