摘要
Solid-liquid phase equilibria of the reciprocal system K+, Mg2+//Cl-, NO3--H2O were studied in the temperature range 5 degrees C-115 degrees C. Phase diagrams obtained at the temperatures of 5 degrees C, 20 degrees C, 40 degrees C and 60 degrees 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 center dot MgCl2.6H(2)O, respectively, with precision better than 1%. Experimental and calculated data on the solid-liquid equilibrium are compared up to the temperature of 115 degrees C. (C) 2013 Elsevier BM. All rights reserved.
