Enthalpies of crystallization of equilibrium solid phases occurring in the system K2SO4-(NH4)2SO4-H2O at 298.15 K

Abstract

The concentration dependences of the differential enthalpies of solution were measured along several crystallization paths in the above-mentioned system, and the enthalpies of crystallization of mixed crystals occurring as a stable solid phase in the system were calculated on this basis. The obtained results confirmed the existence of a region of breaking continuity in the equilibrium solid phases.
