Solid‐liquid phase equilibria in the system KClMgCl2H2O at elevated temperatures. III. Isotherms at 160, 170, and 180°C

Abstract

AbstractExperimental results are reported for the solid‐liquid phase equilibria of the ternary system KClMgCl2H2O at 160, 170, and 180°C. Beyond the known solid phases KCl, KCl · MgCl2 · 6 H2O, and MgCl2 · 4 H2O two further double salts with the composition 1.5 KCl · MgCl2 · 2 H2O and KCl · MgCl2 · 2 H2O have been found. The latter double salt and MgCl2 · 2 H2O form solid solution. The new compounds were characterized by X‐ray powder diffractometry.
