High-Temperature Thermodynamic Properties of Hafnium and Rare Earth Oxide Ceramics
Previous experimental data on the vaporization and high-temperature thermodynamic properties of hafnium and rare earth oxide ceramics are considered here. The La 2 O 3 –Sm 2 O 3 system is for the first time studied at 2323 K using Knudsen effusion mass spectrometry. As a result of this study, the va...

As a result of this study, the vapor composition over ceramic samples under investigation is identified, and concentration dependences of the partial pressures of vapor species over the system under study and condensed-phase thermodynamic properties are determined, namely, the component activities and the excess Gibbs energy. The enthalpy of formation from oxides and excess entropy of the La
