The Thermodynamics of the Aluminum Silicate/Aluminum-Silicon-Oxygen Vapor System

摘要

An investigation of the thermodynamic properties of aluminum silicate, 3Al2O3.2SiO2, over a range of temperatures up to 6000K and pressures up to 1000 atmospheres. Three sets of equilibrium composition equations are used--one representing a pure gas phase, the second a heterogeneous system of gas and condensed alumina, and the third a heterogeneous system of gas and condensed alumina and silica. The gas phase of the heterogeneous chemical systems, like the homogeneous gas phase, comprises 18 gaseous aluminum-silicon-oxygen species. Tabulated summaries give computed values. A conventional Mollier diagram is included in which specific enthalpy is plotted against specific entropy, with cross plots of temperature, pressure, and molecular weight or moles of condensed alumina and silica.
