Thermodynamic properties of compound forming binary liquid sodium-mercury alloy at temperature 673 K have been analyzed as a function of concentration by considering complex using quasi chemical approximation. The surface tension of the alloy has been studied by the compound formation model, Butler equation as improved by Kaptay, and Statistical mechanical approach. The mixing behavior of the alloy is studied in detail with more emphasis on the interaction energy parameters between neighboring atoms of the alloy. The study provides the information of moderately interacting as well as ordering nature on the entire range of concentration of the liquid alloy and the computed theoretical thermodynamic data are in good agreement with the corresponding experimental data at 673 K. The surface tension of the alloy computed predicts deviation from the ideal case.

通过考虑，在 673 K 温度下复合形成二元液态钠汞合金的热力学性质已被分析为浓度的函数使用准化学近似的复数。采用复合形成模型、Kaptay改进的Butler方程和统计力学方法研究了合金的表面张力。详细研究了合金的混合行为，重点研究了合金相邻原子之间的相互作用能参数。该研究提供了在液态合金的整个浓度范围内适度相互作用和有序性的信息，计算出的理论热力学数据与 673 K 下的相应实验数据非常吻合。 计算出的合金表面张力预测与理想情况的偏差。
