    Abstract:

    The thermodynamic database of the Sm2O3-BaO system are of interest for predicting the phase relation of the functional materials. To set up the database of this system, heat capacity of the intermediate compound BaSm2O4 was measured by differential scanning calorimetry and its formation enthalpy from the component oxides at 298 K were measured by high temperature oxide melt solution calorimetry. Using the available phase equilibrium information and thermodynamic data, the thermodynamic optimization on the Sm2O3-BaO system were carried out by means of the CALPHAD technique. A self-consistent database of the Sm2O3-BaO system was set up and was used to calculate the phase diagram and thermodynamic properties of the Sm2O3-BaO system, which will be used for calculations in Sm2O3-BaO containing higher order systems.
