The thermophysical properties of eutectic Ga-Sn-Zn with In additions

Abstract The proposed Ga-Sn-Zn-In liquid alloys could be applied not only in the increasing number of sensors which control devices and help in our daily lives, but also in thermal management systems. The aim of this study is to determine the thermophysical properties of liquid eutectic Ga-Sn-Zn with In additions of 1.0, 5.0, 10.0, 15.0 and 21.4 (wt%). The density and viscosity increases with higher In content in Ga-Sn-Zn-In alloys, and at the same time surface tension and electrical conductivity decreases. According to thermal conductivity and thermoelectric power the obtained experimental results for 1.0 In are higher compare to eutectic Ga-Sn-Zn, and with increasing In content are also decreasing.
