Abstract

Abstract

A new method of calculating activities from binary systems has been developed. The new formulae require that the phase diagrams must contain congruently melting compound and its melting enthalpy is known. Their feasibility is tested by applying the new formulae to In-Sb system. By this method, the activities of an important semi-conductor system Ga-As have also been predicted.
