MICACEOUS IRON OXIDE-MIO
The Micaceous Hematite Iron Oxide Powder is a unique mineral and a very different from other grades of Iron Ore. The production of Micaceous Iron Oxide Powder is very limited in our country. Made using Micaceous Hematite, the Micaceous Iron Oxide Powder is a naturally occurring lamellar form of ferrous oxide for use in manufacturing paint coatings, the thin flake Micaceous Iron Oxide Powder particles appear as sharply defined red translucent platelets. Without doubt, the Micaceous Iron Oxide Powder is the most important barrier pigment used in coatings to protect structural steelworks from corrosion. The Micaceous Iron Oxide Powder has a 100-year record of successful use on many types of steel structures throughout the world. The MIO Powder reflects ultraviolet light, allows water vapor to escape from the substrate, and is chemically resistant.
Quality of MIO
Micaceous iron oxides (MIO) are rather scarce, and significant natural resources are known to be available in Europe (Austria), Asia (China), Australia and Africa, and now in Iran. There are differences in mineralogy and iron content. The most important quality criteria of MIO products according to EN ISO 10601 and ASTM 5532 are:
Content of lamellar particles (minimum 65% for grade A,EN ISO 10601)
Fe2O3 content (min. 85%)
Color of product (grey with metallic sheen)
Particle size distribution (PSD) specified
