Abstract

Using isothermal dissolution method

the phase equilibrium relationship in quaternary system LiCl + NaCl + KCl + H

O and the ternary subsystem LiCl + NaCl + H

O at 288.15 K were investigated. Each phase diagram of two systems was drawn. The phase diagram of LiCl + NaCl + H

O system contains two solid phase regions of crystallization LiCl·2H

O and NaCl. In the phase diagram of LiCl + NaCl + KCl + H

O system

there are three crystallization regions: LiCl·2H

NaCl and KCl respectively. In this paper

the solubilities of phase equilibria in two systems were calculated by Pitzer's model at 288.15 K. The predicted phase diagrams generally agree with the experimental phase diagrams.
