Abstract:
Standard enthalpies of formation of double perovskites REBaCo 2O6-δ (RE = Gd, Pr) from elements, ΔfH i°, at 298 K were determined as a function of their oxygen content using isothermal solution calorimetry. ΔfH GdBaCo2O6-δ ° and ΔfH PrBaCo2O6-δ ° were found to increase linearly with oxygen nonstoichiometry. Such behavior indicates in favor of decrease of relative thermodynamic stability of the double perovskites with oxygen nonstoichiometry. © 2014 Elsevier B.V. All rights reserved.
