Abstract

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.
