In this study, the density and elastic properties of liquid gallium at high pressure and high temperature were measured, and it was found that the results obtained from different equations of state were consistent. Additionally, compared with previous studies, the compression curve of liquid gallium obtained in this study showed a slightly stiffer trend at higher pressures.
The density of liquid metals at high pressure and high-temperature provides fundamental and important information for understanding their compression behavior and elastic properties. In this study, the densities of liquid gallium (Ga) were measured up to 10 GPa and 533 K using the X-ray absorption method combined with an externally heated diamond anvil cell. The elastic properties (the isothermal bulk modulus (K-T0), and its pressure derivative (K-T0')) of liquid Ga were obtained by fitting the density data with three equations of state (EOSs) (Murnaghan, third order Birch-Murnaghan, and Vinet). The K-T0 values of liquid Ga were determined to be 45.7 +/- 1.0-51.7 +/- 1.0 GPa at 500 K assuming K-T0' values of 4-6. The obtained K-T0 or K-T0 ' showed almost the same values regardless of the EOS used. Compared with previous results, the compression curve of liquid Ga obtained in this study had a slightly stiffer trend at higher pressures.
