Abstract

The evaporation of sulfides of chemical compounds making part of processed raw materials having complex genesis is analyzed. Numerous elements in the periodic table are shown to make chemical compounds with sulfur both in condensed and vapor (gaseous) phase. It is established that in the vapor-gas phase many sulfides and sulfide mixtures feature more complex and diverse composition than previously assumed. Beside monomers, sulfide vapor contains various gaseous molecules. Experimental results on the thermodynamics of evaporation and dissociation of sulfides of practically all elements of the periodic table are systematized. A wide range of data is given on vapor pressure, vapor composition, as well as on thermodynamic parameters of gaseous.
