Abstract

An optimized set of thermodynamic functions of liquid CdGa and BiGa alloys is obtained by a least-squares method through optimization of different available experimental data such as phase diagram and thermodynamic properties. These results can be described using a simple model, where the existence of polyatomic self-associates has been considered. The temperature and concentration fluctuations in the long wavelength limit, which are most sensitive to small changes in both temperature and concentration above the miscibility gap, can be described assuming a temperature dependence of the number of self-associated atoms and of the interchange energy.
