Synthesis and Structural Characterization of Nanomanganese Ferrites

The semiconductor spinel ferrite will have the chemical formula as AB2O4 (where A  divalent metal ion like Ni, Mn, Zn, etc and B  Iron metal ion Fe2 + and Fe3 +) and many studies have focused on the synthesis of nanomaterials because of extensive applications due to their novel properties. Magnetite and spinel ferrite nanocrystals are regarded as two of the most important inorganic nanomaterials because of their electronic, optical, electrical, magnetic, and catalytic properties, all of which are different from the properties of their bulk counterparts. [1-2] Among spinel ferrites, manganese ferrite (MnFe2O4) nanoparticles are very important because they have proven to be useful in many magnetic applications, such as recording media devices, drug delivery, ferrofluid, biosensors, and contrastenhancement agents for MRI technology[3-4]. Also find extensive applications in microwave devices, radar, catalysis and magnetic refrigeration systems [5]. Ferrites are synthesized by several methods like ceramic method [6], chemical methods, solvothermal method [7], microwave combustion method [8], thermal treatment method, sol-gel Method [9-10], EDTA-assisted hydrothermal method [11], oxalate co-precipitation technique [12]. Thus Chemical synthesis routes play a crucial role in designing the final product and also they are better and less cumbersome for the production of fine grained mixed oxide products. In this present work, we report the synthesis of nano manganese ferrite by environmental frieldly, low cost co precipitation method. The structural information of manganese ferrite powder is done by XRD characterization. The current work also reports the Texture analysis (preferential orientation of planes), x ray density and crystallite size of manganese ferrite.
