Title: Bismuth-indium system: thermodynamic properties of liquid alloys
Author: T. Kulikova, A. Mayorova, A. Shubin, V. Bykov, K. Shunyaev

Abstract: The thermodynamic activities, the excess integral and partial Gibbs energies, and the enthalpy of mixing for Bi-In melts were studied. For investigation, the methodology of thermodynamic modeling (TM) including the models of an ideal solution (IS) and an ideal solution of interaction products (ISIP) was applied. The modeling was performed for the pressure of 0.1 MPa in an argon atmosphere. The temperature and concentration ranges of study comply with liquid phase region on the Bi-In phase diagram. It has been established the thermodynamic properties of Bi-In melts show negative deviations from Raoult’s law. The mixing enthalpy minimum was observed at x (In) = 0.55 and ΔHE = –1.33 kJ mol–1. In the present study, the lowest values of the excess integral Gibbs free energy were determined as –1.80 and –1.99 kJ mol–1 at the temperatures 600 and 873 K, respectively.
