Abstract:	The study presented here sought to determine the PVT properties of Ice VII at elevated temperatures and pressures up to 60 GPa using a Mao-Bell type diamond anvil cell with an external Mo-wire resistance heater. The unit cells of Ice VII and gold were monitored during the experiment with gold being used as an internal pressure calibrant. Additionally, the melting curve of Ice VII was determined to greater than 40 GPa by using the disappearance of the diffraction pattern of Ice VII to monitor melting in the system. The melting curve for Ice VII from 3 to 60 GPa was found to be accurately related by a Simon equation:
