Abstract : The patent describes a novel process for preparing ferrite and garnet materials by mixing desired metal salts in the form of aqueous solutions, spray drying said aqueous solutions to form a powdery material, presintering the powdery material in an air or oxygen atmosphere to convert the material to mixed oxides having a ferrimagnetic crystal structure, in some cases milling the presintered material to break up the particles, molding into the desired form the resulting powder whether milled or not, and last, sintering the formed material by heating to the desired temperature for sintering.
