Bulk Properties of In-Bi Liquid Alloys 900 K

The bulk properties i.e. thermodynamic as well as microscopic properties of In-Bi liquid alloys at 900 K as a function of In are computed on applying the four-parameter model [FPM]. The analytical expressions for the thermodynamic and microscopic functions of the binary molten alloys at a specified temperature are derived in the framework of FPM. The theoretical results for the excess free energy of mixing, free energy of mixing, activity, enthalpy of mixing, entropy of mixing and concentration fluctuations for In-Bi system at 900 K exhibit well agreement with the correlated experimental data. The concentration dependence of the shot-range order parameter has been theoretically predicted for In-Bi melts at 900 K. The results reveal that In-Bi liquid alloy at 900 K is a feebly interacting ordered alloy.
