Equations of state of six metals above94GPa
Physical Review B
Compression versus pressure at ambient temperature has been measured for tantalum, gold, and platinum to 94 GPa and for aluminum, copper, and tungsten to 153 GPa, in a diamond anvil cell. Standard synchrotron x-ray diffraction accuracy in the volume determination could be achieved to the maximum pressure. The current data set is used to recalibrate the static pressure scale based on the ruby luminescence, confirming recent suggestions of an underestimation of pressure.
