Ferrihydrite

Ferrihydrite is a ubiquitous iron oxyhydroxide mineral. It is found throughout soil and water systems ^[1], important to many industrial applications ^{[2] [3]}, and can even be found within many living organisms including humans^[4]. Ferrihydrite only exists as a nanomaterial, and while it has been classified as a mineral by the IMA since 1971, its structure is still a subject of debate.
