Chemically homogeneous manganese zinc ferrite powders of submicrometer size and desired stoichiometry were achieved using alcoholic dehydration and subsequent calcination of citrate/formate solution. The successful powder preparation was dependent on the water content in the starting solution, the pH of the solution, the amount of alcohol used, and the washing and drying step. Calcination temperature was also critical since the evaporation of ZnO took place above 1000°C. A two‐step calcination process was utilized to develop submicrometer ferrite powders without any Zn loss.
