Abstract
The procedure adopted for preparing the ferrite formation was found to be quite sensitive. The chlorine ion concentration and the pH in the solution has played a crucial role in retaining the initial stoichiometry of the solution in the nanoparticles. This work had the objective of studying the nanoparticle Mn-Zn ferrite obtained by the ferrioelate precursor method. In this process, Mn-Zn ferrite, synthesized through solutions of some specific salts led to the formation of crystalline power (10-30nm as evident from X-ray diffraction analysis) at a temperature of 2000C. The synthesis powders were characterized by X-ray diffractometer for identification of the crystalline phases present, by scanning electron microscopy for identification for their morphological structure and properties, thermogarvimetry and differential thermal analysis for identification of the oxidation/ reduction behaviour upon firing. The fourier transformation infrared spectroscopy (FT-IR) shows two main absorption bands v1 and v2 in the range of 4000-500cm-1and Differential Scanning Calorimetry (DSC) of the Mn0.4Zn0.6Fe2O4 powder at 5000C predicts the exothermic and endothermic reaction with the change in temperature with respect to heat flow. The synthesis route is simple, energy saving and cost effective. Details of the synthesis and characterizations of the resultant products were given.
