Abstract

The reversible galvanic cell: Sn(l), SnO2(s)/CaO-ZrO2/Pb-Sn(l), SnO2(s) (electrolyte) was employed to determine the thermodynamic properties of liquid Pb-Sn alloys in the composition range ofX sn from 0.1 to 0.9 and in the temperature range of 875 to 1100 K. The activities of both tin and lead exhibit only moderate positive deviations from the respective Raoult’s law lines and do not agree with the values reported in the literature.SE, as calculated by combiningHE values of Kleppa andFE values determined in this investigation, are positive and range from 0 to 0.139 eu.
