Abstract
A review is given of the use of free energy‐composition curves in binary systems for determining the range of composition over which a phase, or combination of phases, is stable at a specified temperature (at constant pressure). Phase boundaries may be constructed in the usual temperature‐composition phase diagram from reference to free energy‐composition curves for several temperatures. Examples are given of the construction of phase diagrams for the systems Ca2B2O5–CaSiO3 and Al2O3–Cr2O3. The method described involves an assumption of ideal solution behavior, and is limited in application to systems where ideal solutions are approximàted.
