Lead-free solder alloys: Thermodynamic properties of the (Au + Sb + Sn) and the (Au + Sb) system

► First electromotive force data of the liquid ternary (Au + Sb + Sn) system are reported. ► Partial and integral thermodynamic properties of the (Au + Sb + Sn) system are determined. ► Electromotive force (EMF) data of (Au + Sb) in literature has found to be cited as erroneous in literature. ► Re-measurements with the EMF method have been done in the (Au + Sb) system. ► New values were compared with literature and large differences could be observed.
