Title: Ferromagnetic iron oxides for magnetic recording media
Inventor: AYERS JOSEPH W
IPC: G11B5/706
Filed: 1960-01-01
Abstract: Ferromagnetic iron oxides are prepared by reducing to ferrosoferric oxide in strongly ferromagnetic condition a finely divided iron oxide consisting of crystalline particles of which the major proportion by number are elongated crystalline particles having a maximum dimension of less than 2 microns, a length to width ratio of between 5:1 and 10:1 and a width to thickness ratio of at least 3:1.  The ferrosoferric oxide may be oxidized to gamma ferric oxide.  The starting material may be an artificially prepared ferromagnetic gamma ferric oxide monohydrate or anhydride thereof, which monohydrate may have been prepared by developing a crystalline seeding material in an aqueous reaction medium containing a dissolved ferrous compound and an alkaline reactant, in the presence of metallic iron, a dissolved metal salt that inhibits the development of a goethite crystal structure.  The ferromagnetic oxides of the invention consist of crystalline particles of which the major proportion by number are elongated particles having a maximum dimension of less than 2 microns, a length to width ratio of between 5:1 and 10:1 and a width to thickness ratio of at least 3:1.  In an example ferrous chloride is dissolved in water, dilute sodium hydroxide is added, with agitation, and air is bubbled through the mixture.  This resulting seeding material, together with ferrous chloride or sulphate in aqueous solution, and zinc chloride are introduced into a reactor containing scrap iron.  The contents are agitated and air is blown through.  The precipitate is recovered, washed and dried.  Other inhibiting agents include zinc sulphate, sodium chloride, and ammonium chloride.  Other alkaline reagents include potassium hydroxide, ammonium hydroxide, aniline, and pyridine.  The precipitate may be reduced in a rotary kiln at 316 DEG CC. to 538 DEG C. with hydrogen to form the ferroso-ferric oxide of the invention, and this may be oxidized to the gamma ferric oxide by means of air.
