Evaporation and Thermodynamic Properties of the CeO2–TiO2–ZrO2 System

The processes of the TiO2–CeO2–ZrO2 system evaporation were studied by high-temperature mass spectrometry. The values of the activities of TiO2 and CeO2 at 2250 K indicate a positive deviation TiO2 activity from the ideal behavior and result an increase in the activity coefficient of CeO2 compared to the binary system CeO2–ZrO2.
