摘要
The microstructure of manganese ferrite powder obtained from MnO2 and FeSO4 . 7H(2)O by coprecipitation and aging in isothermal static conditions at temperatures lower than 100 degreesC, has been investigated by X-ray diffraction (XRD), Mossbauer spectroscopy, granulometry and scanning electron microscopy (SEM). The results reveal the influence of the temperature on the particle size distribution as well as on the structure and composition of the ferrite phase. Some magnetic properties of the ferrite powders are presented. (C) 2000 Elsevier Science B.V. All rights reserved.
