Thermodynamic Properties of the RbReO₄ — CsReO₄ System

Abstract

The excess molar Gibbs free energy GE has been determined by mass spectrometric techniques for the solid phase of the system RbReO4 — CsReO4 at 790 K. The liquidus curve of the T—x phase diagram has been determined by thermal analysis. The solidus and the difference between the excess molar Gibbs free energies of the liquid and the solid phases have been calculated.
