Ferric Oxide

Ferric Oxide, also known as iron (iii) oxide and ferrous monoxide, is a dark red inorganic powder with the formula Fe2O3. It is a common pigmentation additive that is used in a variety of industries including glass, personal care, and ceramic glazes and enamels.

Ferric oxide is used as a fertilizer as a source of iron. Plants that require larger amounts of iron also tend to prefer more acidic soils. Such plants include berries, leafy greens, and root vegetables.

Ferric oxide is added to iron, steel, and a variety of metal alloy feed stock.
