Activities of the constituents in one of the Pb-free solder systems, Ag–In–Sn, were studied experimentally using a mass spectrometer. Ion current ratios of Ag to In were measured in the temperature range 1273–1523 K . From the experimental results and the assessed thermodynamic properties of molten Ag–Sn, Ag–In, and In–Sn binary alloys, the excess Gibbs energy of liquid Ag–In–Sn ternary alloy was determined.
