Structural Properties of Ga-Zn Liquid Alloys at 750 K by Molecular Interaction Volume Model

Abstract The Structural properties like concentration-concentration structure factor also known as concentration fluctuations and short-range order parameter of Ga-Zn liquid alloys at 750 K have been studied theoretically. The theoretical model employed is well known statistical mechanical model i.e. molecular interaction volume model (MIVM). The investigative expressions are utilized to explore the thermodynamic functions such as excess free energy of mixing, free energy of mixing and activity, and structural properties i.e. concentration fluctuations and short-range order parameter for Ga-Zn liquid alloys at 750 K. The theoretical data of thermodynamic functions and structural properties are found to be in well agreement with the corresponding experimental data available in the literature. The results show the segregating nature of Ga-Zn liquid alloys at 750 K.
