Abstract:
A thermodynamic dataset was developed for the central part of the Ce–O system covering the range between Ce 2 O 3 and CeO 2 up to about 2000 K. All literature data for the thermodynamic functions, the phase diagram and crystallography were critically assessed. The modeling of the phases takes into account their crystal chemistry including order – disorder behavior. From the dataset, diagrams were calculated for the (1) heat capacities of CeO 2 and Ce 2 O 3 , (2) enthalpy increment of CeO 2 , (3) chemical potentials of oxygen in CeO 2– x , (4) partial enthalpies of oxygen in CeO 2– x , (5) the partial phase diagram of Ce–O and (6) chemical potentials of oxygen in the two-phase areas. These diagrams reproduce fairly well the experimental data from literature.
