Density, surface tension and viscosity of Ga-Sn eutectic based alloys with Zn additions

The density, surface tension and viscosity of Ga-Sn eutectic alloys with additions of 3.6, 10.0, 25.0, 50.0, 75.0, 90.0 wt% of Zn were measured using the discharge crucible method (DC). The above-mentioned physicochemical properties were determined in 323-823 K temperature range. Over a wide range of temperatures the density, surface tension and viscosity of liquid Ga-Sn eutectic based alloys increase with an increase in Zn. The obtained experimental results exhibit a good agreement with the Brillo and Egry model for density, Toop, Kohler, Muggiano and Butler models in the case of surface tension and Sato, Kucharski, Melywen-Hughes, Kozlov, Romanov and Petrov, Gasior and Schick models in the case of viscosity.
