Abstract

The ternary systems with a common cation, NaCl–NaI–Na₂WO₄ and KCl–KI–K₂WO₄, were studied by differential thermal analysis. The composition point of the congruently melting compound NaCl ⋅ Na₂WO₄ formed in the NaCl–Na₂WO₄ system divides the NaI–NaCl–Na₂WO₄ system into two triangles, in each of which there is a ternary eutectic. The characteristics of invariant points were determined, and phase equilibria in the studied systems were described.

摘要

通过差热分析研究了具有共同阳离子的三元体系NaCl–NaI–Na ₂ WO ₄和KCl–KI–K ₂ WO ₄。在NaCl–Na ₂ WO ₄系统中形成的全熔化化合物NaCl·Na ₂ WO ₄的组成点将NaI–NaCl–Na ₂ WO ₄系统分成两个三角形，每个三角形中都有三元共晶。确定不变点的特性，并描述所研究系统中的相平衡。
