Yellow Iron Oxide (Fe2O3.H2O), also known as Hydrated Ferric Oxide, is a yellow odourless powder and insoluble in water. It is manufactured by the precipitation process using leach liquor - a waste from Ilmenite production.

It is one kind of oxides with stable chemical properties. Iron oxide yellow is widely used in painting, scagliola and concrete due to its bright and pure color, good weather proof and high opacity, also can be used as colorant for ink, rubber, paper and so on

Yellow irons can be used where raw color or other raw properties are important to the manufacturing process or color of the unfired product and where a less messy material is desired. High strength, excellent dispersibility and excellent colour stability makes them ideal for use in all kinds of paints under extreme weather and atmospheric conditions.

Yellow iron is not as fluffy and light as black, but more than red. It does not agglomerate as badly as red, but more than black. It is coarser in particle size and does leave some lighter colored residue on a 325 mesh screen (up to 8% in one specimen we tested whereas the others left zero).

Yellow iron is also used in paints, enamels, concrete colorants, plastics, rubber, and paper where permanent yellow is required. It has excellent hiding power, absorbs ultraviolet light, is compatible with a broad range of vehicles, disperses well in aqueous and solvent systems, does not contain heavy metals.
