On The Thermodynamics of Calcite.
An investigation of the thermodynamic properties of calcite, CaCO (subscript) 3, over a range of temperatures up to 6000 deg K and pressures up to 10 (superscript) 5 atmospheres. Two sets of equilibrium composition equations are used--one representing a pure gas phase, the other a heterogeneous system of gas and condensed (solid or liquid) calcia, CaO. 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.
