THE THERMODYNAMICS OF THE BORON CARBIDE BORON-CARBON VAPOR SYSTEM,

Abstract

An investigation of the thermodynamic properties of boron carbide over a range of temperatures up to 6000 deg K 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 (solid or liquid) boron carbide. The gas phase of the heterogenous chemical system, like the homogeneous gas phase, comprises 23 gaseous boron-carbon 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 boron carbide.
