Synthetic iron Oxides

Iron Oxide 1Synthetic Iron Oxides have become increasingly important due to their pure hue, consistent properties, and tinting strength. Single-component forms are mainly produced with red, yellow, orange and black colours. Their composition corresponds to that of minerals hematite, goethite, lepidocrocite, and magnetite. Brown pigments usually consist of mixtures of red and/or yellow and/or black iron oxides. Its current use is mostly in construction, coatings, ceramics, paint, ink, rubber, plastics, cosmetics etc. The building materials industry is the biggest user of Iron Oxide Pigments. Uses include colouring concrete and mortar because of their good dispersability and good tinting strength. They are extensively used in the manufacture of Paving Blocks, Chequered Tiles, Designer Tiles, Stamped Concrete etc.

Paints industry is the second largest user of Iron Oxide Pigments. Most paint applications require use if micronized and dispersible grades of pigments to get optimum colouring effects and maintain paint film strength. Pigments used in Plastics need high purity, tinting strength, high heat resistance and good dispersibility. Special applications include that in Ceramic Colours, Drugs, Cosmetics, Rubber, Brake Linings, Wood Polish, Cork Sheets, Fertilizers and Cattle Feed. New applications include catalysts in petroleum industry, in oil drilling rigs, in compound pigments, copy machine powder, and magnetic differentiate materials.
