摘要

在真空327 ~ 427 K的温度范围内，在Ag - Sn体系中测定了shosanbetsuite （Ag3Sn）的热力学性质（-）Pt|Gr|Ag|RbAg4I5|Ag3Sn, Sn|Gr|Pt（+）。通过对数据的分析，可以计算出Ag3Sn的标准（298.15 K, 105 Pa） ΔfG°，ΔfH°和S°分别为-21238，-18763 J mol-1和187.5 J K - 1 mol-1。

Standard Thermodynamic Properties of Ag3Sn (Shosanbetsuite): EMF Data

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) Δ_fG°, Δ_fH°, and S° of Ag₃Sn: –21238, –18763 J mol^–1, and 187.5 J K^–1 mol^–1, respectively.
