Diiron Trioxide - 1309-37-1

Key Functions: Industrial / Manufacturing, Textile Applications

Diiron Trioxide (Fe2O3) is a naturally occurring metal oxide also known as hematite. Iron is an essential element, and diiron trioxide is widespread in nature. It can be obtained in various polymorphs, the most common being alpha and gamma. It is stable and insoluble in water. It is commonly used as a pigment or colorant in paints, coatings, inks and plastics and is a feedstock for the steel and iron industries. It can be mined and produced naturally or manufactured by synthetic means through oxidation of iron or thermal decomposition of iron salts (7). Natural iron oxides may contain contaminants, reducing their tinting strength compared to the synthetic materials. Non-coloring contaminants are commonly natural extenders used in industry as industrial fillers, including clays, talc and calcium carbonate (2). Therefore, it is important to understand the supplier and source (natural or synthetic) of the specific diiron trioxide being used to determine the potential relevance of any contaminants or additives in the material. 1. Diiron trixode is as a colorant/ pigment in the following applications: Adhesives and sealants Coatings and paint Inks and toners Leather tanning, dyeing Lubricants, greases Paper and board dyeing Plastics Textile dyes 2. Feedstock for the production of steel, iron and other alloys
