DEVELOPMENT OF NANOCRYSTALLINE MAGNESIUM FERRITES AND METHODS FOR PREPARING SAME FROM STEEL ROLLING MILL BY-PRODUCT MILLSCALE
Method for preparing soft cubic ferrites of a general formula MFe2O4 comprising the steps of contacting an iron source comprising metallic iron and/or an oxide of Fe(II), Fe(III), Fe(II/III) and a metal oxide of the general formula MxOy, to form a mixture, wherein the initial stoichiometric ratio of M to iron is in the range from greater than zero to about 2, and wherein M is nickel, magnesium, zinc, or a combination thereof; and calcining the mixture at a temperature range of from about 1000° C. to about 1500° C. in a static air atmosphere, to form a soft cubic ferrite of a general formula MFe2O4, wherein the mixture is not subjected to an oxidation step prior to calcining.
