Thermochemical characteristics of SrCeO3 doped by Eu2O3

For the first time, dissolution enthalpies of strontium cerate doped by europium and a mixture of strontium, cerium, and europium chlorides have been measured by solution calorimetry. Using experimental data, the standard formation enthalpy of SrCe 0.9 Eu 0.1 O 2.95 has been calculated as follows: Δ...

Summary:For the first time, dissolution enthalpies of strontium cerate doped by europium and a mixture of strontium, cerium, and europium chlorides have been measured by solution calorimetry. Using experimental data, the standard formation enthalpy of SrCe 0.9 Eu 0.1 O 2.95 has been calculated as follows: Δ f H ° (298.15 K) = −1692.1 ± 3.9 kJ mol −1 . The stabilization energy of this complex oxide has been calculated and established that its value is negative (Δ st E  = −36.7 ± 4.2 kJ mol −1 ).
