- Goethite - Wikipedia
Goethite is an iron oxyhydroxide containing ferric iron It is the main component of rust and bog iron ore Goethite's hardness ranges from 5 0 to 5 5 on the Mohs Scale, and its specific gravity varies from 3 3 to 4 3 The mineral forms prismatic needle-like crystals ("needle ironstone" [3]) but is more typically massive [2] Feroxyhyte and lepidocrocite are both polymorphs of the iron

- Goethite - an overview | ScienceDirect Topics
Goethite (α-FeOOH) is defined as the most common iron oxyhydroxide, characterized by its antiferromagnetic properties and a Néel temperature of about 120°C, and it plays a significant role in low-temperature oxidation processes It dehydrates to hematite at approximately 300°C and is a component of manganese nodules and Pacific red clay facies AI generated definition based on
