Research done at the Bureau of Mines has produced calorimetric data for the low temperature heat capacity from 12 to 312 k and the high temperature relative enthalpy from 400 to 800 k for aluminum sulfide (al2s3). The heat capacity measurments yielded s deg298 = 27.927 +- 0.05 Cal k-1 mol-1 for the standard entropy at 298.15 K (1 cal = 4.1840 J). The standard enthalpy of formation at 298.15 K, ahf deg298 = 155.6 +- 0.9 Kcal mol-1, was determined by hydrochloric acid solution calorimetry. The results were combined with the published data for pure aluminum and sulfur to obtain a complete set of thermodynamic data for al2s3 from 0 to 900 k at appropriate temperature intervals.
