Vaporization and Thermochemical Study of SrCeO₃(s) and SrCe_0.95Yb_0.05O₃(s) by Knudsen Effusion Mass Spectrometry

Abstract:

The vaporization of samples in the SrO-CeO2 system was investigated by the use of Knudsen effusion mass spectrometry in the temperature range of 1494 K – 1988 K. Partial pressures of the gaseous species O2, CeO2, Sr, and SrO were determined over the samples investigated. The partial pressures of the species were used for the evaluation of thermodynamic activities of CeO2 and SrO in the samples at 1800 K. The enthalpy of formation of SrCeO3(s) was obtained as
fH°(298 K) = -1644 ± 21 kJ mol-1. The Gibbs energy of formation of SrCeO3(s) from SrO(s) and CeO2(s) resulted as
fG°(1800 K) = -12.5 ± 2.8 kJ mol-1 for the phase field {SrCeO3 + ss of SrO in CeO2} and
fG°(1800 K) = -13.7 ± 2.1 kJ mol-1 for the phase field {SrCeO3 + SrO}. The influence of the Yb concentration in the perovskite phase SrCe0.95Yb0.05O3 on the CeO2(s) activity was studied as well. The thermodynamic properties obtained in the present study are discussed on the basis of the data available in literature.
