dc.description.abstractHeat capacities were measured from 5 to 350°K for two pyrrhotites at the iron‐rich limit (Fe1.000S) and the sulfur‐rich limit (Fe0.877S) of the homogeneity range. The heat‐capacity curves follow the normal sigmoid shape with the exception of an upward trend for Fe1.000S above 300°K, and two small, broad humps for Fe0.877S near 8 and 30°K. From these data the entropy and enthalpy functions were calculated. At 298.15°K the values of Cp, S°☒S0°, and (H°☒H0°)/T are 12.08, 14.415, and 7.496 cal/mole °K, respectively, for Fe1.000S, and 11.92, 14.529, and 7.396 cal/mole °K for Fe0.877S. The values on FeS are lower by approximately 10% over the range 58 to 296°K than those previously reported in the literature.en_US
