摘要：

The Powders of Ni-Zn ferrite having the chemical formula Ni ((0.6)) Zn ((0.4)) Fe2O4 were synthesized by using chemical coprecipitation method and followed by heat treatment at 130 degrees C, 600 degrees C & 900 degrees C. X-ray powder diffractometry (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) were carried out to investigate structural and chemical aspects of Ni-Zn ferrite. The cubic spinel structure in single phase has been confirmed by X ray diffraction. The average crystallite size was calculated from the line broadening in XRD pattern. The sizes of the particles were increased with sintering temperature. The micro structural features of the samples were studied using scanning electron microscopy (SEM) technique. The IR Spectra measured in the range of 4000-400 cm(-1) exhibit symmetric stretching mode of Fe2O4 and ZnO4 tetrahedral at 669.7 cm(-1) and 545.6 cm(-1). (C) 2013 The Authors.
