ON THE THERMODYNAMICS OF CALCITE.

Abstract

The thermodynamics of calcite, CaCO3, are investigated over a range of temperatures up to 6000 K and pressures up to 100,000 atmospheres. Two sets of equilibrium composition equations are used--one representing a pure gas phase, the other a heterogeneous system of gas and condensed (i.e., solid or liquid) calcia, CaO. The gas phase of the heterogeneous chemical system, like the homogeneous gas phase, comprises 13 gaseous calcium-carbonoxygen species. The results of the computational program are presented in both tabular and graphic form. The latter is a conventional Mollier diagram in which specific enthalpy is plotted against specific entropy, with cross plots of temperature, pressure, and molecular weight. (Author)
