Abstract
Solid-liquid phase equilibria of the reciprocal system K +, Mg2 +//Clâ, NO3â-H2O were studied in the temperature range 5 °C-115 °C. Phase diagrams obtained at the temperatures of 5 °C, 20 °C, 40 °C and 60 °C are presented. Data for higher temperatures are presented in a table. A semi-empirical model for the description of solid-liquid equilibrium for KNO3-MgCl2 diagonal of this system was developed. The model allows calculating the material balance of crystallization of KNO3, KCl, and KCl·MgCl2·6H2O, respectively, with precision better than 1%. Experimental and calculated data on the solid-liquid equilibrium are compared up to the temperature of 115 °C.
