Red & Yellow Iron Oxide

Natural Iron Oxides are derived from Hematite, which is a Red Iron Oxide mineral; Limonites, which vary from yellow to brown, such as ochers, siennas, and umbers; and Magnetite, which is black Iron Oxide. Synthetic Iron Oxide Pigments are produced from basic chemicals. The three major methods for the manufacture of synthetic Iron Oxides are thermal decomposition of iron salts or iron compounds, precipitation of iron salts usually accompanied by oxidation, and reduction of organic compounds by iron. Synthetic 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. Read more . . .

Red & Yellow Iron Oxide Usages:

• The building materials industry is the biggest user of Iron Oxide Pigments. Uses include colouring concrete and mortar because of their good dispersibility and good tinting strength. They are extensively used in the manufacture of Paving Blocks, Chequered Tiles, Stamped Concrete and 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. Read more . . .
