N2 - In this study, the formation mechanism, particle morphology and magnetic properties of 3BaO·2CoO·12Fe2O3 (Co 2Z) ferrite obtained using the molten salt method (Li 2SO4-Na2SO4) were investigated using X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, and superconducting quantum interference device magnetometer. The results of this investigation indicate that the crystalline phases and morphology were sensitive to (1) the starting oxide ratio to molten salt, and (2) the reaction temperatures. Hexagonal plate-like Co2Z particles were obtained with a starting oxides/molten salt ratio of 7/3. The coercivity of the Co2Z ferrite powder synthesized in this study was much lower than that produced in previous studies.
