Solid–liquid equilibria in the NaCl–SrCl2–H2O system at 288.15 K

Phase Equilibria in the Quaternary Systems (KCl + CaCl2 + SrCl2 + H2O) and (LiCl + NaCl + SrCl2 + H2O) at 288.15 K and 0.1 MPa

“…The quaternary system (LiCl + NaCl + SrCl 2 + H 2 O) includes three ternary subsystems corresponding to (LiCl + NaCl + H 2 O), (NaCl + SrCl 2 + H 2 O), and (LiCl + SrCl 2 + H 2 O). Table shows the comparisons of the liquid-phase composition and the corresponding solid phase on the invariant points of the three ternary subsystems in this work and in the literature. ,,,− It is found that the solubility on the invariant point of the ternary system (LiCl + NaCl + H 2 O) at 288.15 K in this work is consistent with the literature data. , Additionally, the equilibrated solid phases are both LiCl·2H 2 O + NaCl. It is observed that the experimental data at the invariant point of the ternary system (NaCl + SrCl 2 + H 2 O) at 288.15 K show good agreement with the literature, and the equilibrated solid phases are both SrCl 2 ·6H 2 O + NaCl.…”

The results of the study on the invariant point of the ternary system (NaCl + SrCl 2 + H 2 O) at 291.15 K 10 also provide evidence for the data reliability in this experiment.…”

Phase Equilibria and Phase Diagrams for the Aqueous Ternary System Containing Sodium, Chloride, and Metaborate Ions at 288.15 and 308.15 K and 0.1 MPa

“…(c) Both of these phase diagrams include three isothermal curves AE 1 , E 1 E 2 , and BE 2 at 288. 15 On the basis of the densities and refractive indices in Table 3, diagram of the physicochemical properties with sodium chloride composition in the solution as the abscissa at 288.15 and 308.15 K is constructed in Figure 3. As can be seen from the gure, the densities and refractive indices in the ternary system at two temperatures uniformly increased primarily from single salt points A or A ′ of NaBO 2 to reach the rst cosaturated invariant points E 1 or E 1 ′ of (Smt + Te) and then dropped signi cantly with the increase of sodium chloride concentration to reach another cosaturated invariant points E 2 or E 2 ′ of (Te + Ha), and further sharply decreased to another single salt points B or B′ of NaCl.…”

Phase Equilibria in the Ternary System NaCl–SrCl2–H2O (273 and 308 K) and Quaternary System LiCl–NaCl–SrCl2–H2O (308 K)

“…Many experimental and theoretical studies on systems containing strontium and lithium have been conducted. For the ternary system NaCl−SrCl 2 −H 2 O, it was first studied at multiple temperatures by Assarsson, 5 and the specific solubility data at 291 K, 333 K, and 373 K were given as well as at 288 K, 6 298 K, 7,8 323 K, 9 and 348 K. 10 It was found that the system has only one invariant point at these temperatures, and the equilibrium solid phases are SrCl 2 •6H 2 O (SrCl 2 •2H 2 O at 348−373 K) and NaCl. The predicted solubilities of this system at 288 and 298 K were carried out by using the Pitzer model, and the calculated data agreed well with the experimental data.…”
