DEVELOPMENT OF NICKEL-ZINC FERRITES AND METHODS FOR PREPARING SAME USING IRON-OXIDE BYPRODUCTS OF STEEL INDUSTRY
Method for preparing soft cubic ferrites of a general formula Ma(1-i)MbiFe2O4 comprising the steps of contacting an iron source a first metal oxide having the general formula MbxOy and a second metal oxide having the general formula MaxOy to form a mixture, wherein the stoichiometric ratio of (Ma+Mb) to iron is in the range from greater than zero to about 2, and wherein Ma and Mb comprise 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 Ma(1-i)MbiFe2O4, wherein the mixture is not subjected to an oxidation step or a reduction step prior to contacting and wherein calcining comprises a single stage heat treatment.
