OBS

Polvo de color rojo oscuro, denso, que se encuentra en la naturaleza (hematites) y que puede obtenerse por calcinación del sulfato ferroso o deshidratación del hidróxico férrico. Tiene aplicaciones en metalurgia, como pigmento en pinturas, en productos cauchíferos y como mordiente en la industria textil.

OBS

El óxido férrico o sesquióxido constituye el colcótar.

This spinel mineral [chromite] can show a considerable variation in composition with ... ferric iron substituting for the chromium.

CONT

... iron, Fe, and manganese ... usually occur in groundwater in solutions as ferrous, Fe2+, and manganous, Mn2+, ions. When exposed to air, they form the insoluble ferric, Fe3+, and manganic ... forms, making the water turbid ...

CONT

Si l'on considère les deux types d'ions Fe++ et Fe+++ on constate que [...] le fer ferreux bivalent est relativement plus abondant que le fer ferrique trivalent [...]

CONT

[...] la formation de ces gisements de fer rubané cessa brusquement il y a environ 1,8 milliard d'années, lorsque l'atmosphère se chargea d'oxygène. La mobilité du fer diminua à mesure que le fer ferreux s'oxydait en fer ferrique, moins soluble.
