Abstract
New data on the solubilities of solids and the compositions of immiscible l iquid fluids in the Na3PO4-Na2HPO4-H2O system at 350 degreesC and under vap or pressure were experimentally derived. Transition of the metastable liqui d-liquid phase separation region to a stability region occurs through the a ppearance of immiscibility in the fluid phase in the presence of a solid an d through joining immiscibility regions originating from boundary binaries.
