Abstract:

The purpose of the study is the thermodynamic investigation of beryllia, Be0, 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 beryllia. The gas phase of the heterogeneous chemical system, like the homogeneous gas phase, comprises 15 gaseous beryllium-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 beryllia.
