gothite's Usage Examples:

By heating freshly prepared red ferric hydrate with water under 5000 atmospheres pressure Ruff (Ber., 1901, 34, p. 34 1 7) obtained definite hydrates corresponding to the minerals limonite (30°-42, 5°), gothite (4 2.5°-62, 5°), and hydrohaematite (above 62.5°).

Ferric oxide or iron sesquioxide, Fe203, constitutes the valuable ores red haematite and specular iron; the minerals brown haematite or limonite, and gothite and also iron rust are hydrated forms. It is obtained as a steel-grey crystalline powder by igniting the oxide or any ferric salt containing a volatile acid.

Enclosures of other minerals (rutile, chlorite, haematite, gothite, actinolite, asbestos and many others) are extremely frequent in crystals of quartz.

Limonite and the related minerals, turgite, 2Fe20 3 +H 2 O, and gothite, Fe 2 0 3 +H20, are grouped together under the term " brown haematite."

The metallic glitter of avanturine or sun-stone (q.v.) is due to the enclosed scales of gothite and certain other minerals.

Gothite occurs with other iron oxides, especially limonite and hematite, and when found in sufficient quantity is mined with these as an ore of iron.

GOTHITE, or Goethite, a mineral composed of an iron hydrate, Fe203.H20, crystallizing in the orthorhombic system and isomorphous with diaspore and manganite.
