Abstract

Abstract Well crystallized lepidocrocite (γ-FeOOH) with high phase purity can be prepared by precipitation from homogeneous solution. FeCl2 is oxidized with NaClO3 while heating the common solution slowly from 20 to 75 °C. Due to the buffer pyridine/HCl the pH-value changes only from 6.3 to 5.3. The product with the specific surface of about 16 m2/g has been characterized by several methods, especially by thermal analysis.
