Abstract:
The study considers zirconium nitride over a range of temperatures up to 6000 deg K and pressures up to 100 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 ZrN. The gas phase of the heterogeneous chemical system, like the homogeneous gas phase, comprises eight gaseous zirconium-nitrogen species. Computational results are presented in both graphic and tabular form. The former 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 ZrN.
