Abstract Scope |
Liquid metals are new functional materials that are being studied for a number of applications, including soft electronics [1], medicine [2], and thermal management of various systems [3]. In the case of any of those applications the thermophysical properties of the materials have to be assessed. We propose the use of non-toxic Ga-Sn-Zn alloys. Based on thermodynamic assessment, the density, viscosity and surface tension has been calculated via different models, including the Egry model for density, Sato, Kucharski, Moelywen-Hughes, Kozlov, Romanov and Petrov, Schick and Gasior models in the case of viscosity and Kohler, Toop, Muggiano and Butler models for surface tension. Experiments performed using the discharge crucible method are in good agreement with the models.
