Abstract (AI)
The transformations ia-x the iron oxide-hydroxide system have been inter-preted in a rational crystallochemical manner, some bring characterized as topotactic and some as non-topotacfic. Crystallographic measure-ments have been made on the more reactive or metastable phases, parti-cularly on the "green rusts. " The oxyhydroxides ~-]~eOOFI and ~-FeOOH have been examined more fully, but data on ald the phases have been checked. New data on transformations, such as FeCOa---> FeO and Fe(OH)~-+ FeO are reported.
Key Findings
1
Crystallographic measurements were made on reactive or metastable phases, particularly on 'green rusts'.
2
New transformation data are reported for FeCO3 → FeO and Fe(OH)2 → FeO.
3
The oxyhydroxides γ-FeOOH and α-FeOOH were examined more fully and data across all phases were checked.
4
Transformations in the iron oxide-hydroxide system are interpreted using a rational crystallochemical framework distinguishing topotactic and non-topotactic reactions.
Research Object
Iron oxides and hydroxides (the iron oxide–hydroxide system, including green rusts, FeCO3, FeO, Fe(OH)2, α-FeOOH, β-FeOOH and related phases)
Research Subject
Structural relationships and phase transformations among these iron oxide–hydroxide phases, including crystallographic characterization, topotactic versus non-topotactic transformation mechanisms, and reactivity/metastability of phases
