The unit-cell volume of copper (Cu) has been measured by synchrotron x-ray at pressures and temperatures of up to 8.1 GPa and 1100 K. From pressure-volume-temperature (P-V-T) measurements, thermoelastic parameters of Cu were derived based on a modified high-T Birch-Murnaghan equation of state and a thermal pressure approach. The ambient bulk modulus derived from this work is comparable to previously reported value, whereas all other thermoelastic parameters of Cu have never been determined before. These results extend our knowledge of the fundamental thermophysical properties on Cu.
