• Ferrihydrite - Wikipedia

    en.wikipedia.org/wiki/Ferrihydrite Ferrihydrite (Fh) is a widespread hydrous ferric oxyhydroxide mineral at the Earth's surface, and a likely constituent in extraterrestrial materials. It forms in several types of environments, from freshwater to marine systems, aquifers to hydrothermal hot springs and scales, soils, and areas affected by mining.

    www.sciencedirect.com/topics/earth-and-planetary-sciences/ferrihydrite Ferrihydrite is a precursor for goethite and hematite. Its large surface area and reactivity allow it to serve as sink for nutrients and metals. In addition, the higher surface area enhances the contact between water and ferrihydrite. Another iron-based material is the ferrite which is formed by combination of transition metal and iron oxide.

    sites.temple.edu/strongingroup/research-projects/ferrihydrite Understanding the Structure of Ferrihydrite. Ferrihydrite is a nanoscale iron oxyhydroxide (Fe-O-OH) mineral that is ubiquitous in water and soil systems, and plays an important role in geochemical processes and the fate of contaminants.
  • Ferrihydrite - an overview | ScienceDirect Topics

    www.sciencedirect.com/topics/.../ferrihydrite Ferrihydrite is the precursor for most iron oxides in soil, and it subsequently transforms to more stable phases such as goethite (Feitknecht and Michaelis, 1962). The structure of ferrihydrite has been the subject of considerable interest and several structural models have been proposed for the mineral.
  • Ferrihydrite: Mineral information, data and localities.

    www.mindat.org/min-1493.html It is a metastable nanomineral precursor to other minerals, e.g. hematite, goethite. There are no known deposits of ferrihydrite before the Pleistocene. Two structure models have been proposed: the "f-phase" model and the "akdalaite" model; the first one seems to be correct (Paktunc et al., 2013).
