Solid-Liquid Equilibria in the Ternary System KCl-KBr-H2O at 348 K
Phase equilibria in the ternary system KCl-KBr-H2O at 348 K were studied by the isothermal solution dissolution equilibrium method. The solubilities of salts and densities of saturated solutions in the ternary system were determined experimentally. The equilibrium solid phases were also determined by chemical analysis and X-ray powder diffraction. Using the experimental data, the phase diagram of the ternary system was obtained, which comprises one univariant curve and one stationary phase in the crystallization field of K(Cl,Br). The ternary system was a solid solution type. The density transformation rules were discussed simply, and the relationship equations of equilibrium liquid phase and the solid phase composition data were fitted with a cubic equation.
