Abstract

The Tl–Er–Te ternary system was studied in the Tl₂Te–Tl₂Te₃–TlErTe₂ composition region by the emf method and X-ray powder diffractions analysis. The partial thermodynamic functions of ErTe and Er in alloys were determined from the emf measurements. Using the constructed diagram of solid-phase equilibria, the potential-forming reactions responsible for the above partial molar quantities were determined, and the standard thermodynamic functions of formation and standard entropies of the Tl₉ErTe₆ and TlErTe₂ compounds were calculated.

摘要

通过电动势法和X射线粉末衍射分析研究了Tl ₂ Te–Tl ₂ Te ₃ –TlErTe ₂组成区域中的Tl–Er–Te三元体系。根据电动势测量确定合金中ErTe和Er的部分热力学函数。使用固相平衡图，确定了造成上述部分摩尔量的电势形成反应，并计算了Tl ₉ ErTe ₆和TlErTe ₂化合物的形成标准热力学函数和标准熵。
