Notes
Actual yellow iron oxides are around 85% Fe2O3 and about 12% LOI with some impurities (e.g. SiO2, CaO).
Any form of iron can normally be used to source Fe for the fired product. In ceramics, yellow irons are used where its raw color or other raw properties are important to the manufacturing process or color of the unfired product.
Yellow iron is 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.
One process of manufacture involves precipitation of ferric oxyhydroxide followed by purification through washing, drying and milling.
Yellow is a less stable oxide of iron. Yellow ochre clay contains yellow iron oxide.
