✦ Synopsis

The coexistence of the crystalline substance AB, partially dissociating upon melting, with its melt in the system A--AB was described using a new procedure which does not assume any hypothetical equilibrium. By fitting the experimentally determined phase diagram of the system A--AB with the theoretical temperatures of primary crystallisation an original method for the calculation of the characteristic thermodynamic quantities, e.g. the degree of dissociation of the compound AB in the melt and the dissociation enthalpy of the crystalline substance AB was developed. The proposed approach was applied in numerous systems and the obtained results were compared with those of the volume properties analysis.
