Formation enthalpy of BaCe0.7Nd0.2In0.1O2.85
  In this paper for the first time we synthesized the compound BaCe0.7Nd0.2In0.1O2.85 by solid-state reaction. The phase has orthorhombic structure (space group Pmcn). We also measured the standard formation enthalpies of BaCe0.7Nd0.2In0.1O2.85 by solution calorimetry in 1 M HCl with 0.1 M KI. We determined the stability of Nd(In)-doped barium cerate with respect to mixtures of binary oxides. On the basis of these data we established that above-mentioned mixed oxide is thermodynamically stable with respect to their decomposition into binary oxides at room temperatures. We also established that BaCe0.7Nd0.2In0.1O2.85 oxide is thermodynamically favoured than BaCe0.8Nd0.2O2.9.
