ABSTRACT: The concentration dependent thermodynamic behaviour of Mg-In-Cd melts at 850 K has been analysed in terms of the excess free energy of mixing, free energy of mixing, activity coefficient and activity of first element i.e. Mg on applying MIVM known as molecular interaction volume model. The computations of the mentioned thermodynamic functions require the input parameters, which are ascertained from the parameters needed for the concerned binary system at 850 K. The theoretical values for the excess free energy of mixing, free energy of mixing and activity for In-Mg at 923 K, In-Cd at 800 K and Cd-Mg at 923 K are in well agreement with the corresponding experimental results. The concentration dependence of the excess free energy of mixing, free energy of mixing, activity coefficient and activity of first element i.e. Mg for Mg-In-Cd system at 850 K for three cross-sections namely

= 3:2, 2:3 and 1:4 indicate that Mg-In-Cd melts at 850 K is more stable for cross-section 3:2 followed by 2:3 and 1:4 respectively.
