The solubility of the RbCl–CsCl–H2O ternary system has been investigated at the temperature range from 298.15 to 348.15 K by two different methods, namely, the Flow-Cloud-Point (FCP) method and the Isothermal Dissolve Equilibrium (IDE) method. The measured solubility for this ternary system at 298.15 K by FCP method is consistent with the reported result in literature. The measured solubility results for this ternary system at 323.15 K by the FCP and IDE, two different methods that are consistent with each other, which indicated the results are more reliable. Meanwhile, the measured liquid–wet solid–solid lines proved that the equilibrium solid phases are two types of solid solutions (Rb,Cs)Cl(ss) and (Cs,Rb)Cl(ss) rather than pure salts (RbCl and CsCl) reported in literature. For the first time, the solubility of the RbCl–CsCl–H2O ternary system at 308.15 and 348.15 K has been measured by IDE method. The measured results shown that the equilibrated solid phases in this ternary system at 308.15 and 348.15 K are two types of solid solution (Rb,Cs)Cl(ss) and (Cs,Rb)Cl(ss), at RbCl rich side and CsCl rich side, respectively.

包含RbCl–CsCl–H 2 O系统的固溶体的溶解度测量从T = 298.15至348.15 K
通过两种不同的方法，即流动浊点（FCP）方法和等温溶解平衡（IDE），研究了RbCl–CsCl–H 2 O三元体系在298.15至348.15 K温度范围内的溶解度。方法。通过FCP方法测得的该三元体系在298.15 K的溶解度与文献报道的结果一致。通过FCP和IDE在323.15 K下测得的该三元系统的溶解度结果，这两种方法彼此一致，表明结果更可靠。同时，测得的液体-湿固-固线证明平衡固相是两种类型的固溶体（Rb，Cs）Cl （ss）和（Cs，Rb）Cl （ss）而不是文献中报道的纯盐（RbCl和CsCl）。通过IDE方法首次测量了RbCl–CsCl–H 2 O三元体系在308.15和348.15 K的溶解度。测量结果表明，该三元体系在308.15和348.15 K处的平衡固相是（Rb，Cs）Cl （ss）和（Cs，Rb）Cl （ss）的两种固溶体，富RbCl处和CsCl丰富的一面，分别。
