Characterization of Magnesium Ferrite, MgFe2O4

Magnesium ferrite, MgFe2O4, was prepared by solid state reaction method. Structural and vibrational characteristics of the sample were studied by X-ray diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopic methods. Morphological features of the sample were investigated by Scanning Electron Microscope (SEM). Simultaneous Thermogravimetric and Differential Thermal Analysis (TG-DTA) measurement was carried out to investigate the high temperature phases of the sample in the temperature range 303 K – 873 K (30C - 600C). Electrical conductivities and dielectric constants of the pelletized sample were investigated in the temperature range 300 K - 973 K (27C - 700C). It was found that the sample is a thermally high resistance material
