The thermophysical properties of Ga-Pb liquid alloys

The higher amount of energy generated from renewable energy sources has caused the search for new storage energy materials. In this study, the density, surface tension, and viscosity of liquid Ga-Pb alloys with 2, 30, 60, and 94.6 (at. %) Pb additions were determined, in the temperature range from 573 to 1023 K. The isotherm of thermophysical properties were presented for a temperature of 873 K, along with literature data, and compared with values obtained from the Brillo and Egry models for density, the Butler model for surface tension, and the Sato, Gasior, Kaptay and Kozlov-Romanov-Pertov models for viscosity. The obtained result shows very good agreement with the literature data and models.
