Synthetic red iron oxide are the most common oxide colour and have the highest amount of iron. Due to their pure hue, consistent properties, and tinting strength, they have become increasingly important in various fields of applications.
They are available commercially as a soft and very fine dry powder made by grinding ore material or heat processing ferrous/ferric sulphate or ferric hydroxide.
Applications/Uses : Synthetic Red Iron Oxides are high-quality inorganic colour pigments with excellent colour stability, light fastness, weather stability and chemical resistance. Ideally suited for use in paints & Coatings, rubber, paper, polishing rouge, ceramic, linoleum, wall paper, plastic asphalt, cement colours, mosaic tiles and Construction - flooring. The building materials industry is the biggest user of Iron Oxide Pigments, because of their good dispersibility and good tinting strength. It’s uses include colouring concrete, mortar, Paving Blocks, Chequered Tiles, Designer Tiles, Stamped Concrete etc.
It is also plays a role in foundry core making and ferrite, which is used by the electronic industries.
