The pressure-volume-temperature (PVT) equation of state (EOS) of MgO is widely used as a
pressure scale in static compression experiments. However, there are remarkable
inconsistencies among different previously proposed MgO pressure scales. We calculated
the PVT EOS of MgO up to 300 GPa and 3000 K based on experimental shock Hugoniot
data and a simple thermal pressure model within the Mie-Grüneisen-type analysis
framework. All of the parameters used can be measured experimentally with high …
