“…By using electromotive force, Kleppa 16 measured activity of Sn in the Au-Sn liquid at 823 K, and Kameda et al 17 did it at 1,223 K and 973 K. Howard and Hager 18 measured it at 1,873 K using mass spectrometry. These data, from different sources, show good agreement with one another.…”

The phase diagram of the Au-In-Sn system is of importance in developing materials of high performance in electronic packaging as well as in simulating the interfacial reaction between Sn-In and Au. By using the calculation of phase diagram (CALPHAD) method, phase equilibria in the Au-Sn binary system has been optimized based on experimental thermodynamic property and recently renewed phase boundaries. Combined with two binary systems, Au-In and In-Sn, in addition to the reported experimental isothermal section of the Au-In-Sn system, the Au-In-Sn ternary system has been modeled, and three isothermal sections at 300 K, 500 K, and 700 K and three vertical sections, Au-In 0.2 Sn 0.8 , Au-In 0.5 Sn 0.5 , and Au-In 0.7 Sn 0.3 , of the Au-In-Sn ternary system have been further calculated.

Highlights► A full thermodynamic description of the liquid ternary Au–Cu–Sn system is reported. ► The electromotive force method with a liquid electrolyte was used to determine the activity of tin in the alloys. ► The partial free energies of tin in this system were calculated from the obtained EMF values. ► The Gibbs–Duhem integration was used to calculate the integral Gibbs free energy and integral enthalpy of the entire system.

“…Using equations (1), (3), and (4) , the activities of tin, the partial Gibbs free energies, partial enthalpies and partial entropies were calculated and are listed in table 2 . Figure 4 shows the activities of tin for two limiting binary systems Au–Sn and Bi–Sn taken from the literature [11,12] , and for three cross-sections Au:Bi = 2:1, Au:Bi = 1:1, and Au:Bi = 1:2 of the ternary Au–Bi–Sn system obtained in this work. All the data are shown at constant temperature 800 K. It can be seen that the activity of Sn exhibits a very strong negative deviation from Raoult’s law both in the binary Au–Sn system and the ternary Au–Bi–Sn system.…”
