Abstract

The accepted solidus [5] on the In-rich side of the In-Ga phase diagram has been shown to be thermodynamically infeasible. A solidus consistent with the liquidus and microcalorimetric heats of solution measurements [6] has been constructed with an analysis utilising a linear programming computer technique. The thermodynamic interaction parameter α [defined by αij=In γi/(1−Ni)2] have been determined as functions of temperature and composition for the liquid and In-rich solid solutions. The liquid and solid solutions are found to be not far from regular. The In-rich solvus curve has also been computed.
