High pressure and high temperature fluid fugacities

Journal Article · · Geochim. Cosmochim. Acta; (United States)
High-temperature and high-pressure shock-wave data on fluids (pure species) have been combined with low-temperature and low-pressure data to generate a corresponding state equation in the virial format in reduced pressure and temperature for many species. The equation is then modified to obtain a similar equation of state for H/sub 2/O. The fugacities of the pure species in the C-H-O system can be calculated to a temperature of 3000 K and to a pressure of 1 megabar. However, dissociation of the pure species may invalidate the data over certain pressure-temperature ranges.
