Abstract: The magnetic properties of magnetite prepared by chemical coprecipitation are closely related to the precipitator mixing method, concentration of solution and molar ratio of Fe2+/Fe3+ and Fe2+/OH- ions etc. When the alkaline solution is slowly added to the mixed aqueous solution containing ferric and ferrous ions, the process of formation of Fe3O4 consists of two steps.
