Abstract

The formation of nucleus iron-oxygen structures in Fe0-H2O-O2 systems has been investigated. It has been shown that temperature affects the rate of iron(II) oxidation and, accordingly, the composition of components involved in phase formation. At 10°C, only nucleus structures of protolepidocrocites are formed on the surface; at 20–40°C, structures of protolepidocrocites and ferrihydrite; and at 50–70°C, structures of magnetite and FeO. The analysis of thermodynamic functions has revealed the most probable formation reactions of nucleus iron-oxygen structures and the optimal conditions for the structure formation in morphological series.
