This dissertation has the goal of showing the efficacy of an UNIQUAC
inspired method to calculate activities in liquid binary systems and assess its
suitability in solid binary systems. Literature data was used in optimizing objective
functions to obtain reasonable binary parameters. The results were up to standard
for liquid systems. The results of some solid systems were below expectations,
namely the alloys Au-Cu, Cd-Mg and Fe-Mn. Besides comparing literature data
with the theoretical calculations, the activities were utilized in an iterative method
for solid-liquid equilibrium calculation in two binary systems: Cu-Ni and Bi-Sb. The
calculations for the Cu-Ni systems were bad. On the other hand, the Bi-Sb showed
good agreement with experimental data.
