The electrical conductivity relaxation curve of the SrxTi0.30Fe0.70O3 (x=0.90 and 1.00) at 700 °C

Description

In this dataset are presented exemplary curves used for analysis of the electrical conductivity relaxation (ECR) mesurement of the SrxTi0.30Fe0.70O3 (x=0.90, 1.00) materials. The applied measuring temperature were 700 °C. Studies were performed in a small tube furnace (internal diameter ~20 mm) with 64 cm³ gas volume. During the four-point single frequency electrochemical impedance spectroscopy measurement (1 Hz), the oxygen partial pressures were changed from 20% O₂ to 10% O₂ and the reverse.

Both cases incorporation and removal of oxygen are included.
