ABSTRACT:
A process for electrolytically producing a metallic oxide for a ferrite comprising the steps of electrolyzing an inorganic ammonium salt solution of 2-20% containing 0.01-5% of fluoride compound as an electrode with metals or mixture of metals necessary for producing the ferrite as an anode and graphite as a cathode to produce the hydroxide of the metal used as the anode, oxidizing and separating the hydroxide, and then drying and calcining the hydroxide. Thus, a low silica metal oxide of uniform composition is produced by mixing the composition of a ferrite to be produced with iron and/or manganese or iron and/or manganese in case of producing the metal oxide for the ferrite, and electrolyzing various metal with the resultant mixture as an anode.
