“…of Equilibrium Phases According to current views [2,23,29], crystals of pand 3 d -metal oxide compounds grow via incorporation of CFCs into their surface layer. The composition and structure of CFCs are governed by the state of metal ions in solution.…”

“…In such solutions, the composition of Fe 3+ AHCs is [Fe(OH) 3 (H 2 O) 3 ] 0 [30]. According to Raspopov et al [29], these AHCs form binuclear complexes of composition [Fe 2 (OH) 6 (H 2 O) 4 ] 0 (CFC-1), each consisting of two edge-shared octahedra (Fig. 7c).…”

Crystallization, coalescence, chemical reactions, and phase transformations in disperse systems based on hydrous Ti, Mn, Co, Fe, and Zn oxides during heat treatment in solutions of various ionic compositions are analyzed. The results indicate that the transformations in disperse systems follow the dissolution-precipitation mechanism and are accompanied by mass transfer between the solid phase and solution. Reactions are considered, using iron(III) oxyhydroxides as an example, that occur at the solution-crystal interface, and the possible compositions of crystal-forming complexes and the elementary reactions involved in the incorporation of the complexes into different faces of growing crystals of the equilibrium phase are established.

“…It follows from the electroneutrality condition that, in weakly acidic, neutral, and weakly alkaline media (2 < pH < 10), the {100} faces of α -Fe 2 O 3 consist of alternating layers of water molecules (Fig. According to Raspopov et al [29], these AHCs form binuclear complexes of composition [Fe 2 (OH) 6 (H 2 O) 4 ] 0 (CFC-1), each consisting of two edge-shared octahedra (Fig. 7b).…”
