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

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

The processes of the TiO 2 –CeO 2 –ZrO 2 system evaporation were studied by high-temperature mass spectrometry. The values of the activities of TiO 2 and CeO 2 at 2250 K indicate a positive deviation TiO 2 activity from the ideal behavior and result an increase in the activity coefficient of CeO 2 c...

Zusammenfassung:The processes of the TiO 2 –CeO 2 –ZrO 2 system evaporation were studied by high-temperature mass spectrometry. The values of the activities of TiO 2 and CeO 2 at 2250 K indicate a positive deviation TiO 2 activity from the ideal behavior and result an increase in the activity coefficient of CeO 2 compared to the binary system CeO 2 –ZrO 2 .
