Description
The heat contents of the Sb-S and Sb2S3-FeS systems were measured by a drop-calorimeter in the concentration ranges of NS=0 to 0.6 and NFeS=0 to 1, and in the temperature ranges of 750 to 1350 K and 750 to 1500 K, respectively.<BR>The method of quantitative thermal analysis was applied to calculation of the thermodynamic quantities such as the activity of the components and the heat and entropy of mixing in the liquid Sb-S and Sb2S3-FeS systems. A considerably large positive deviation from a Raoultian behaviour was observed in aSb of the Sb-S system at 1300 K, while the sulfur pressure increased drastically at about NS=0.6 where the compound Sb2S3 is located. Large positive deviations from Raoultian behaviours were also observed in aSb<SUB>2S3</SUB> and aFeS of the Sb2S3-FeS system at 1473 K in the high concentration range FeS above NFeS=0.7.
