Sulfide capacities of Na/sub 2/O-SiO/sub 2/ melts at 1473 and 1623/sup 0/K were calculated a priori from a model using free energies of formation of Na/sub 2/S and Na/sub 2/O and the activities of Na/sub 2/O in the binary Na/sub 2/O-SiO/sub 2/ melts. Our calculations are in excellent agreement with available experimental data and appear to be more accurate than currently used empirical predictions of sulfide capacities, based on correlations with optical basicities using Pauling electronegativities.
