Summary
The study presents experimental data of the viscosity and specific heat capacity of the near eutectic gallium-indium-tin alloy. Viscosity data cover the temperature range from the alloy’s melting point 283.85 K (10.70 °C) to about 370.47 K (97.32 °C). Two independent teams using a capillarity viscosimeter and an oscillating cup viscosimeter obtain almost identical values. Below 373 K (100 °C) the data follow the Arrhenius correlation. Specific heat capacity data result from differential scanning calorimetry measurements and reach from 236 K (-37 °C) to 340 K (67 °C). The Neumann-Kopp rule gives neither for the solid nor for the liquid state a satisfactory representation of the data. Approximation functions represent these two regions separately in excellent manner. The study discusses several issues related to the thermophysical properties, namely melting and crystallisation, and a possible liquid-to-liquid crossover.
