Abstract

Fe2O(SO4)2 is a secondary product of the decomposition of FeSO4⋅H2O. Part I of this study presents results on the synthesis of Fe2O(SO4)2 in gaseous environment containing either low or high concentration of oxygen. In this paper the existence of differences between the structures of Fe2O(SO4)2 and Fe2(SO4)3 is proved on the basis of a detailed thermal study of Fe2O(SO4)2 upon dynamic heating (differential thermal analysis) and upon isothermal heating (thermal-analytic balance) in various gaseous environments as well as by presenting kinetic data on the processes of decomposition of both compounds.
