Ferrites are materials with multiple applications due to their unique magnetic properties. For this investigation, magnetite (Fe3O4) particles were synthesized by chemical co-precipitation by varying the temperature of the medium. From magnetite, maghemite (Fe2O3) was synthesized by applying a thermal treatment. Magnetite and maghemite were used along with reactive- grade zinc oxide (ZnO) particles as precursors for the synthesis of zinc ferrite (ZnFe2O4) particles by the mechanical grinding technique. During the grinding, the grinding speed and composition of the precursors varied. Finally, the zinc ferrite samples were given post-grinding thermal treatment. Mechanical grinding assisted by thermal treatment proved to be the most effective in the synthesis of zinc ferrite particles. The synthesized samples were characterized by X-ray diffraction for analysis using the Match software.
