Vapour pressure measurements in the Ce-Te system were carried out employing the isopiestic method. Four sets of isopiestic experimental runs were performed for the temperature range 805 – 1035 K for the composition span from ∼65 to ∼75 at% Te covering the Ce-Te phase diagram region encompassing the intermetallic compounds CeTe2, Ce2Te5 and CeTe3. Activity measurements, partial enthalpy of mixing of tellurium for CeTe2 intermetallic compound and Gibbs energy of the reaction between CeTe2 and Ce2Te5 are reported. A few phase boundaries of the Ce-Te phase diagram were redefined with the measured data and reported.
期刊介绍:
Thermochimica Acta publishes original research contributions covering all aspects of thermoanalytical and calorimetric methods and their application to experimental chemistry, physics, biology and engineering. The journal aims to span the whole range from fundamental research to practical application.
The journal focuses on the research that advances physical and analytical science of thermal phenomena. Therefore, the manuscripts are expected to provide important insights into the thermal phenomena studied or to propose significant improvements of analytical or computational techniques employed in thermal studies. Manuscripts that report the results of routine thermal measurements are not suitable for publication in Thermochimica Acta.
The journal particularly welcomes papers from newly emerging areas as well as from the traditional strength areas:
- New and improved instrumentation and methods
- Thermal properties and behavior of materials
- Kinetics of thermally stimulated processes
