Density, surface tension and viscosity of Ga-Sn alloys

In this work, the viscosity, density and surface tension of liquid Ga-Sn alloys were measured using the discharge crucible method (DC), and the effect of alloy composition on the temperature dependences of these properties are shown. The measurements were performed over a temperature range of 323-773 K. The viscosity and density of Ga-Sn alloys across a wide range of temperatures increase with increasing Sn content in the alloy, while surface tension decreases. The obtained experimental results were in very good agreement with the Prasad and Butler models for surface tension, and the Kozlov-Romanov-Petrov and Gasior models for viscosity.
