资源简介：
In this dataset are presented D* values designated based on the electrical conductivity relaxation (ECR) mesurement of the SrxTi0.30Fe0.70O3 (x=0.90, 0.95, 1.00) materials. The applied temperatures were 800 °C, 750 °C, 700 °C, 650 °C, and 600 °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.
D* was designated for both cases incorporation and removal of oxygen.
