Abstract : The standard thermodynamic properties of phases in the lime-alumina-silica-water system between 273.15 and 1800 K at 101.325 kPa(1atm) were evaluated from published experimental data. Phases included in the compilation are boehmite, diaspore, gibbsite, kaolinite, dickite, halloysite, andalusite, kyanite, sillimanite, Ca-A1 clinopyroxene, anorthite, gehlenite, grossular, prehnite, zoiste, margarite, wollastomite, cyclowollastonite (=pseudowollastonite), larnite, Ca olivine, hatrurite, and rankinite. The properties include heat capacity, entropy, relative enthalpy, and the Gibbs energy function of the phases and the enthalpies, Gibbs energies, and equilibrium constants for formation both from the elements and the oxides. Tabulated values are given at 50 K intervals with the 2-sigma confidence limit at 250 K intervals. Summaries for each phase give the temperature-dependent functions for heat capacity, entropy, and relative entropy and the experimental data used in the final evaluation. (Author)
