Cobalt ferrite (CoFe2O4) nano-particles were successfully prepared using microwave heating by polyol method. Using a 2.45 GHz multimode microwave synthesis unit, a mixture of Cobalt nitrate and Ferric nitrate were heated for 2 minutes after being dissolved and mixed in ethylene glycol which act as a reducing agent and as a solvent. The produced cobalt ferrite was characterized using Scanning Electron Microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD), Thermogravemetric analysis (TGA) and saturation magnetization measurements. The microwave prepared ferrite material was pure ferrite nano-crystalline phase with size ranging from 13 to 25 nm.
