Abstract

Iron monosulfides, Fe1-xS (0 < x < 0.125), are extremely complex in their chemical and physical behaviours, which are largely attributed to their nonstoichiometric nature and myriad superstructures. The chemical composition of Fe1-xS affects the polymorph formation for iron monosulfides, their mineral reactivity, surface sulfur fugacity, and thermal expansion. In this paper, the effects of cation vacancy and crystal superstructure on the thermodynamics of iron monosulfides are reviewed and discussed.
