“…Deng et al , researched the solubility relationships of the ternary systems NaBr + SrBr 2 + H 2 O, KBr + SrBr 2 + H 2 O, and LiBr + SrBr 2 + H 2 O at 288.15 K; at the same time, they used Pitzer and HW model to simulate the thermodynamic properties and predict the solubility data, and the predicted data agreed well with the measured solubilities. Our group has also studied a lot about phase equilibria of the systems containing magnesium bromide and strontium bromide, such as the ternary system CaBr 2 + MgBr 2 + H 2 O (348 K), the quinary system NaBr + KBr + MgBr 2 + SrBr 2 + H 2 O (323 K), and some of its subsystems (273, 298, 323, and 348 K); − the results show that MgBr 2 can form double salts with KBr and CaBr 2 .…”

The stable phase equilibria of the ternary system MgBr2 + SrBr2 + H2O at 288 and 308 K were studied with the isothermal dissolution equilibrium method. The compositions of solutions and solid phases have been determined and the equilibrium solid phases at the invariant points were identified with the aid of the X-ray diffraction method. The phase diagrams of this system at 288 and 308 K were both constructed in terms of experimental results. Two stable phase diagrams show that this system is hydrate type I at two temperatures without formation of a solid solution or complex salt. Both the phase diagrams are composed of one invariant point, two univariate curves, and two crystallization regions (SrBr2·6H2O and MgBr2·6H2O). The equilibrium solid phases of the invariant point at 288 and 308 K are both SrBr2·6H2O and MgBr2·6H2O, respectively. Combining the Pitzer single-salt parameters of MgBr2 and SrBr2 reported in the literatures, the unreported mixing ion-interaction parameters θMg,Sr and ΨMg,Sr,Br at 288 and 308 K were fitted with the measured values in this study using the Pitzer equations. The agreement between the experimental values and calculated results in the ternary system MgBr2 + SrBr2 + H2O at 288 and 308 K shows that the parameters fitted with solubilities are reliable.

“…Moreover, aiming at the utilization of strontium-rich underground brine in the Sichuan Basin, research on phase equilibrium of ternary systems NaCl–SrCl 2 –H 2 O and KCl–SrCl 2 –H 2 O at 348 K was carried out . Regarding the phase diagram of water–salt containing strontium bromide, the ternary subsystem mainly includes MgBr 2 –SrBr 2 –H 2 O at 298 and 323 K, and NaBr–SrBr 2 –H 2 O and KBr–SrBr 2 –H 2 O at 288, 308, and 323 K. − The phase equilibrium in quaternary system NaBr–KBr–SrBr 2 –H 2 O at 348 K was investigated, which indicated that strontium bromide hexahydrate can be widely present at a temperature within 348 K …”

This work describes the solid−liquid phase equilibria in the ternary system SrCl 2 −SrBr 2 −H 2 O at T = 273, 298, and 323 K based on the method of isothermal dissolution equilibrium. Since saturated liquid phases and humid residue compositions for a series of synthetic brines were determined simultaneously, the measured equilibrium tie lines were constructed. At the same time, the corresponding equilibrium solid phases were identified by using the Schreinemakers' method supplemented with X-ray powder diffraction. The experimental phase diagrams of the system SrCl 2 −SrBr 2 −H 2 O at T = 273, 298, and 323 K were established according to the theory of phase diagram for water salt system. It is found that the type of the system is classified as completely solid solution type due to formation of solid solution Sr(Cl, Br) 2 •6H 2 O. The phase diagrams of the ternary system SrCl 2 −SrBr 2 −H 2 O at 273, 298, and 323 K are constituted of one univariant solubility curve and one solid crystalline phase region corresponding to Sr(Cl, Br) 2 •6H 2 O, without any invariant point. The Pitzer equation was selected to calculate the solubility data in the ternary system SrCl 2 −SrBr 2 −H 2 O at T = 273, 298, and 323 K. The solubility modeling approach achieved good agreement with experimental solubility data.

In this paper, the stable phase equilibrium data of the ternary system CaBr 2 -SrBr 2 -H 2 O 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 CaBr 2 −SrBr 2 −H 2 O 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 CaBr 2 •6H 2 O + SrBr 2 •6H 2 O at 273 and 298 K and those identified as CaBr 2 •4H 2 O + SrBr 2 •6H 2 O 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.
