Synthesis of y-Ferric Oxide by Sol-Gel Technique

There are several well established methods available to produce Y-ferric oxide. The industrial practice consists of a "three step process", involving (i) precipitation ofgoethite to produce haematite, (ii) reduction of haematite to magnetite and (iii) controlled oxidation of magnetite to y-ferric oxide. The proposed work describes the sythesis of y-ferric oxide, using iron (II) acetate by sol-gel route. It involves a single step calcination to get y-ferric oxide with improved magnetic properties. Similarly, I % cobalt-substituted y-ferric oxide has also been prepared. XRD pattern and morphology using SEM are recorded. The synthesis offers a simple and cheap method to prepare y-ferric oxide.
