Manganese substituted magnesium ferrites having stoichiometric composition Mg 1-x Mn x Fe 2 O 4 with x ranging from 0.0 to 1.0 were prepared sugarcane juice based Sol-gel method. X-ray diffraction was used to characterize the structure and phases present respectively. It was found that of all ferrite compositions at 800°C led to cubes of the ferrite grains and that there was single phase spinel structure. The Xray diffraction patterns revealed the presence of (311)
…………………………………………………………………………………………………….... Introduction:-Nanoscale crystalline mixed metal oxides are synthesized by several mechanical and chemical methods. The main objective is to reduce the costs of chemical synthesis and to produce materials for technological applications [1][2][3][4][5]. Among the several methods, high random distribution of the metal ions or complexes are based on the use of a matrix are fix (solution or gel). This increases the chemical homogeneity and reduces the segregation of a particular metal during the processing and crystallization of the mixed metal oxides [6][7]. In these chemical methods, the metal ions are immobilized on an atomic scale, which allows obtaining oxides at lower temperatures than solid state reaction. Due to the immobilization, the metal ions react with each other with a minimum diffusion; consequently, it is possible to synthesize homogeneous and stoichiometric oxides [8][9]. Sol-gel is one of the best techniques with these characteristics [10]. In these techniques, the particle size can be controlled by the formation and aggregation of the particles in the starting sol, which is dependent on the concentration of reagents, temperature, pH, electro negativity of the metals, solvent etc. [11][12][13][14][15]. Besides the versatility and simplicity water is the most polar solvent, the aqueous solution-gel method can offer a better chemical homogeneity compared to other solvents. Therefore, aqueous solution-gel synthesis method was tested to produce cheap nanocrystalline powders.This new technique is based on the use of sugarcane juice as the chelating agent, and it stands out by its simplicity, low processing cost and reduces environmental pollution, using sugarcane juice and metal nitrates nano-crystalline mixed metal oxides are synthesized. The process is similar to previous work [16]. In this paper, the chemical route is similar but sugarcane juice is used as the chelating agent for the synthesis of nanoscale Mn Substituted MgFe 2 O 4 for the study of electrical resistivity.
