The compression of solid CO2 at 296 K to 10 GPa

Abstract

The volume of solid CO2 was measured at 296 K from 1 to 10 GPa using a high pressure, x-ray diffraction technique. The compression of NaF was used as the pressure gauge. The data are converted to the velocity plane and linearly fit. The volumes and bulk moduli are calculated from the fit as a function of pressure. Previous compression studies are discussed and a recent a priori calculation is shown to agree well with the present data.
