The solid-liquid equilibria in the ternary system LiBr-SrBr2 -H2O at 273.15, 308.15, and 323.15 K were studied by isothermal dissolution equilibrium method in this work. At three different temperatures, the ternary system LiBr-SrBr2-H2O belongs to hydrate type I saturation. The phase diagram at 273.15 K includes one cosaturation point, two univariant curves, and two crystallization zones corresponding to LiBr center dot 2H(2)O and LiBr-SrBr2 center dot 6H(2)O. The other two phase diagrams contain two cosaturation points, three univariant curves, and three crystallization fields corresponding to LiBr center dot 2H(2)O, SrBr2 center dot 2H(2)O, and SrBr2 center dot 6H(2)O at 308.15 K and LiBr center dot 2H(2)O, SrBr2 center dot 2H(2)O, and SrBr2 center dot 6H(2)O at 323.15 K, respectively. Lithium bromide has an obvious salting-out effect on strontium bromide. The crystallization area of lithium bromide hydrate is the smallest, and lithium bromide is difficult to crystallize out of the solution at different temperatures.
