Abstract:

The purpose of this study is the thermodynamic investigation of alumina, A1203, over a range of temperatures up to 6000K and pressures up to 1000 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 alumina. The gas phase of the heterogeneous chemical system, like the homogeneous gas phase, comprises 12 gaseous aluminum-oxygen 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 or moles of condensed alumina.
