摘要：
In this study, solid-liquid equilibrium measurements in ternary system SrBr2-MgBr2-H2O at (298 and 323) K are conducted using the isothermal dissolution equilibrium method. The mass fraction of every component of the equilibrium liquid phase in the system is determined at (298 and 323) K. Based on the experimental results, the phase diagrams and density-composition diagrams are plotted. Results show that no double salt or solid solution is formed in the system SrBr2-MgBr2-H2O at (298 and 323) K. The ternary system SrBr2-MgBr2-H2O at (298 and 323) K has one invariant point, two univariant curves, and there are two solid-liquid two-phase areas that correspond to strontium bromide hexahydrate (SrBr2 center dot 6H(2)O) and magnesium bromide hexahydrate (MgBr2 center dot 6H(2)O).
