Phase equilibria in the ternary system KCI-SrCl_2-H_2O at 25 ℃ was studied by using the isothermal method. Density and refractive index of the solution were also determined. The phase diagram was plotted according to the experimental data. In the equilibrium phase diagram of KCI-SrC12-H20, there is one invariantpoint, two univariant curves and two regions of crystallization: KCI and SrCl_2·6H_2O. In the invariant point, the composition of the liquid phase (mass fraction, w_B) was W_(KCI) 7.22%, W_(SrCl)_2 32.31%, the solid phase was KCI and SrCl_2·6H_2O. Neither double salts nor solid solutions between KCI and SrCl_2·6H_2O were found, and dehydration of SrCl_2·6H_2O didn't occur in the system. The system is a simple eutectic type.
