Available in PDF, EPUB and Kindle. Book excerpt: The study reports the thermodynamic investigation of zirconia, Zr02, over a range of temperatures up to 6000 K and pressures up to 1000 atmospheres. Two sets of equilibrium composition equations are usedone representing a pure gas phase, the other a heterogeneous system of gas and condensed (i.e., solid or liquid) zirconia. The gas phase of the heterogeneous chemical system, like the homogeneous gas phase, comprises five gaseous zirconium-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 irconia.
