Abstract:
The purpose of this study is the thermodynamic investigation of aluminum, Al, over a range of temperatures up to 6000° K and pressures up to 103 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) aluminum. The gas phase of the heterogeneous chemical system, like the homogeneous gas phase, comprises 3 gaseous species.The results of the computational program are presented in both tabular and graphic form. The latter comprises (a) 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 aluminum, (b) a plot of volume versus temperature for aluminum, and (c) a plot of vaporization temperature for aluminum and graphite at various temperatures
