Abstract

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.

Ce-Te 二元系统的热力学研究

采用等压法对 Ce-Te 系统中的蒸汽压力进行了测量。在 805 - 1035 K 的温度范围内进行了四组等压实验，碲的组成跨度从 ∼65 到 ∼75 at% Te，涵盖了包括金属间化合物 CeTe2、Ce2Te5 和 CeTe3 的 Ce-Te 相图区域。报告了活性测量结果、CeTe2 金属间化合物碲的部分混合焓以及 CeTe2 和 Ce2Te5 反应的吉布斯能。根据测量数据重新定义了 Ce-Te 相图的几个相界，并进行了报告。

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
