Abstract

An equation of state (EOS) of rhenium, an in situ pressure calibrant for internally heated diamond anvil cells (IHDAC), was analyzed. The isothermal (EOS) of rhenium at ambient temperature was combined with volume data collected at randomly distributed, simultaneous high pressure-temperature conditions. Synchrotron radiation x-ray diffraction in conjunction with an IHDAC equipped with a rhenium internal resistive heater developed at the Cornell High Energy Synchrotron Source was used to collect data. The results show that the rhenium can be used as a convenient pressure calibrant although the accuracy of it depends on many factors including the reliability of the pressure scale at high temperature.
