Electrical conductivity relaxation measurements - oxidation and reduction of BaCe0.6Zr0.2Y0.1Tb0.1O3-δ

Description

The dataset consists of 2 main catalogs: measurements performed for oxidation/reduction in dry conditions and in humid conditions. For Electrical Conductivity Relaxation (ECR) measurements, platinum reversible electrodes were applied in a four-probe arrangement and the sample was measured in the ProboStat™ measurement system. The ECR measurements were performed in the temperature range of 500-800 ℃ after switching oxygen partial pressure between pO2 = 0.1 atm. and pO2 = 10^(-3) atm.

Each file name contains information on the date of the measurement, temperature, the investigated process (oxidation or reduction), and the electrical current used. Sometimes one measurement had to be divided into parts. In that case, the information about the part of the measurement data collection is included in the file name.

The measurements enabled the determination of the chemical surface exchange coefficient of oxygen and the corresponding activation energies for oxidation and reduction in dry and wet atmospheres for the BaCe0.6Zr0.2Y0.1Tb0.1O3-δ sample.
