Abstract
Thermodynamic properties of shosanbetsuite (Ag3Sn) are first determined in the Ag–Sn system in a galvanic cell (–) Pt|Gr|Ag|RbAg4I5|Ag3Sn, Sn|Gr|Pt (+) within the temperature range of 327–427 K in vacuum. Analysis of the data makes it possible to calculate the standard (298.15 K, 105 Pa) ΔfG°, ΔfH°, and S° of Ag3Sn: –21238, –18763 J mol–1, and 187.5 J K–1 mol–1, respectively.
