Liquid metals are a group of functional materials of growing importance in the recent years. In this work, the density, viscosity and surface tension of liquid Ga-Sn-Zn alloys for compositions with the Sn/Zn ratio of 3/1, 1/1 and 1/3 with Ga additions have been determined by the discharge crucible method. An attempt was done to describe the abovementioned properties as a function of temperature and composition. The new thermophysical property data were compared to the values predicted by models. The Moelwyn-Hughes, Kozlov-Romanov-Petrov, Sato, Schick and Gasior models for viscosity, and for density, the Brillo and Egry and ideal solution models were applied. The surface tension of binary liquid alloys was analysed in the framework of the Butler and Quasi Chemical Approximation for regular solution (QCA), while to describe the surface tension of ternary melts, the models of Butler, Toop, Kohler and Muggianu were used.

液态金属是近年来越来越重要的一组功能材料。在这项工作中，采用放电坩埚法测定了 Sn/Zn 比为 3/1、1/1 和 1/3 并添加 Ga 的液态 Ga-Sn-Zn 合金的密度、粘度和表面张力. 已尝试将上述特性描述为温度和组成的函数。将新的热物理特性数据与模型预测的值进行比较。应用了 Moelwyn-Hughes、Kozlov-Romanov-Petrov、Sato、Schick 和 Gasior 模型的粘度，而对于密度，应用了 Brillo 和 Egry 以及理想溶液模型。在常规溶液的巴特勒和准化学近似 (QCA) 的框架内分析了二元液态合金的表面张力，
