Thermophysical properties of the liquid Ga-Sn-Zn eutectic alloy

Higher demand and increased working temperatures in the energy production sector have prompted work on the development of new, more efficient and higher performance cooling for liquid metals. However, a lack of understanding of the thermophysical properties of the materials involved has limited the potential applications of such materials. This study presents the results of the temperature dependency of density, surface tension, viscosity, electrical conductivity, thermoelectric power and thermal conductivity for eutectic Ga-Sn-Zn. The conducted measurements show higher melting temperature and surface tension, and lower thermal expansion coefficient, density, viscosity, electrical conductivity and thermal conductivity of eutectic Ga-Sn-Zn compared to eutectic Ga-In-Sn.
