摘要：The solid-liquid-phase equilibria of quaternarysystem K+, Mg2+, Na+//Cl--H2O and its three ternary subsystems K+, Mg2+//Cl--H2O; Mg2+, Na+//Cl--H2O; and K+, Na+//Cl--H2O at278.15 and 288.15 K were studied by an isothermal solution equilibriummethod. The quaternary system K+, Mg2+, Na+//Cl--H2O includes twoinvariant points, five univariant curves, and four crystallizationregions. The double salt KCl & BULL;MgCl2 & BULL;6H(2)O is found in the quaternary system but no solid solution. Basedon the experimental results and the multitemperature comparison, theorder of the solubilities of the single salts is KCl < NaCl
