Abstract
The preparation of BaCeO3 doped by yttrium and indium oxides (BaCe0.6Y0.3In0.1O2.8) has been performed by solid-state reaction from BaCO3, CeO2, Y2O3, and In2O3. The compound BaCe0.6Y0.3In0.1O2.8 has been synthesized for the first time. The X-ray measurements have shown that BaCe0.6Y0.3In0.1O2.8 has an orthorhombic structure (space group Pmcn). The standard molar enthalpy of formation of BaCe0.6Y0.3In0.1O2.8 has been determined by solution calorimetry combining standard molar enthalpies of dissolution of BaCe0.6Y0.3In0.1O2.8 and BaCl2Â +Â 0.6CeCl3Â +Â 0.3YCl3Â +Â 0.1InCl3 mixtures in 1Â M HCl with 0.1Â M KI at 298.15Â K and literature data. It has been found out that the mixed oxide mentioned above is thermodynamically stable as to its decomposition into binary oxides at room temperature. It has also been shown that BaCe0.6Y0.3In0.1O2.8 was more thermodynamically favored than BaCe0.9In0.1O2.95.
