Mineral solubilities of salts in the three quaternary systems: LiCl–NaCl–MgCl2–H2O, LiCl–KCl–MgCl2–H2O and Li2SO4–K2SO4–MgSO4–H2O at 288.15 K

The (solid + liquid) phase equilibria of the NaBr + KBr + SrBr2 + H2O quaternary system and two subsystems (NaBr + SrBr2 + H2O and KBr + SrBr2 + H2O) were studied at T = 323 K using the isothermal dissolution method. With the solubility values of each system, the stable phase diagrams of these systems were drawn. It shows that there is neither solid solution nor double salt in the diagrams. The three systems are all of the hydrate type I, and only one invariant point is found in the phase diagrams of the three systems.

Solubility and phase diagram investigation of the ternary system LiCl–SrCl2–H2O at 323.15 K and 348.15 K

The two quaternary systems NaBr–SrBr2–MgBr2–H2O and KBr–SrBr2–MgBr2–H2O at 323 K were constructed by the isothermal dissolution equilibrium method. The mass fraction of every component of the equilibrium liquid phase in the two systems at 323 K was calculated. The phase diagrams and water content diagrams were plotted in accordance with the Janecke indices of salts and water. The system NaBr–SrBr2–MgBr2–H2O at 323 K has two invariant points, five univariant curves, and four solid phase crystallization areas, which correspond to strontium bromide hexahydrate (SrBr2·6H2O), magnesium bromide hexahydrate (MgBr2·6H2O), sodium bromide (NaBr), and sodium bromide dihydrate (NaBr·2H2O). The system KBr–SrBr2–MgBr2–H2O at 323 K has double salt (KBr·MgBr2·6H2O) without solid solution formation. It has two invariant points, five univariant curves, and four solid phase crystallization areas corresponding to strontium bromide hexahydrate (SrBr2·6H2O), magnesium bromide hexahydrate (MgBr2·6H2O), double salt (KBr·MgBr2·6...

Solid–Liquid Equilibria in the Quaternary Systems NaBr–SrBr2–MgBr2–H2O and KBr–SrBr2–MgBr2–H2O at 323 K

The stable phase equilibria of the quaternary systems LiCl–KCl–MgCl2–H2O and Li2B4O7–Na2B4O7–MgB4O7–H2O at 273 K were studied using isothermal stable equilibrium method and the solubilities of the salts in the systems were also determined in turn. According to the experimental data and the corresponding equilibrium solid phases, the isothermal solubility diagrams, water content diagrams about two systems at 273 K were plotted, respectively. The first system has two double salts LiCl·MgCl2·7H2O and KCl·MgCl2·6H2O at 273 K, and its isothermal phase diagram of this system includes three invariant points, seven univariate curves, and five crystalline areas, those are LiCl·2H2O, MgCl2·6H2O, KCl, LiCl·MgCl2·7H2O and KCl·MgCl2·6H2O, respectively. The second system has no complex salt or solid solution and the system belongs to a simple cosaturated type, and its stable phase diagram is constituted by an invariant point, three univariant solubility curves, and three solid phase crystalline regions, where the three...
