In this paper, the stable phase equilibrium data of the ternary system CaBr₂-SrBr₂-H₂O at T = 273, 298, and 323 K and 101.3 kPa have been determined by isothermal the dissolution equilibrium method. The phase diagrams of them at the investigated temperatures have been drawn. It is found that the isothermal phase diagrams of the CaBr₂–SrBr₂–H₂O system at T = 273, 298, and 323 K are classified as a simple co-saturation type consisting of an invariant point and two univariant curves. The equilibrium solid phases corresponding to an invariant point of the system were detected as CaBr₂·6H₂O + SrBr₂·6H₂O at 273 and 298 K and those identified as CaBr₂·4H₂O + SrBr₂·6H₂O at 323 K. In this system, calcium bromide exhibits a strong salting-out effect on strontium bromide. Furthermore, isothermal solubilities at three temperatures were compared and discussed.

三元系CaBr ₂ -SrBr ₂ -H ₂ O在273、298和323 K时的固液相平衡

本文通过等温溶解平衡法确定了三元体系CaBr ₂ -SrBr ₂ -H ₂ O在T = 273、298和323 K和101.3 kPa时的稳定相平衡数据。绘制了它们在研究温度下的相图。我们发现，CaBr ₂ -SrBr ₂ -H ₂ O系统在T = 273、298和323 K时的等温相图被归类为由不变点和两条单变量曲线组成的简单共饱和类型。检测到对应于系统不变点的平衡固相为CaBr ₂ ·6H _2。O + SrBr ₂ ·6H ₂ O不连到273和298 K和那些鉴定为CABR ₂ ·4H ₂ O + SrBr ₂ ·6H ₂ O不连到323 K.在本系统中，溴化钙呈现上溴化锶很强的盐析效应。此外，对三种温度下的等温溶解度进行了比较和讨论。
