Thermogravimetric analysis data of hydration in air and nitrogen for BaCe0.6Zr0.2Y0.1M0.1O3-δ (M = Fe, Pr, Tb)
Description
The dataset consists of 6 files of thermogravimetric analysis (TGA) data. The TGA experiments of hydration for BaCe0.6Zr0.2Y0.1Fe0.1O3-δ (BCZYFe), BaCe0.6Zr0.2Y0.1Pr0.1O3-δ (BCZYPr), and BaCe0.6Zr0.2Y0.1Tb0.1O3-δ (BCZYTb) were conducted on Netzsch STA 449.
The analyzed powders were annealed at 800 ℃ for 5 h in dry air (pH2O ~ 10^(-5) atm.) to remove water and surface carbon dioxide, then cooled to 300 ℃ and kept at this temperature for 2 h. Subsequently, the dried gas was switched to the humidified air (pH2O ≈ 0.023 atm.). Each sample remained in the wet atmosphere for ≈ 2 h and then the gas was switched back to the dry air for approximately 1 h. An analogous procedure was used in a nitrogen atmosphere.
The difference between the mass recorded in the dry and wet atmospheres allowed one to estimate the relative mass change, which enabled the analysis of the water uptake mechanism in the investigated samples and the determination of the proton defects’ concentration after hydration in air.
