Microwave route for synthesis of ferrites at nano dimension is a technology for ceramic manufacturing, which integrates the synthetic technology for information storage materials. Number of synthetic methods is in the literature, out of these, microwave firing could be an interesting because of its simplicity, eco-friendly and less time consuming. This microwave firing is used for synthesis of magnesium ferrite materials. Nanosized MgFe₂O₄ is synthesized by microwave route using urea as a fuel. Magnesium oxalates and iron oxalates were prepared by dissolving magnesium and iron salt in oxalic acid solution. These two oxalates with urea are irradiated with microwaves using urea as a fuel to get cubic MgFe₂O₄ nanoparticles. The structure of the prepared nano ferrite is studied by X-ray diffraction (XRD) technique. This study shows that the formation of crystalline cubic structure. Morphology of magnesium ferrite is viewed by Scanning electron micrograph (SEM) tool. This SEM image shows spherical particles with compact and globular arrangement. Infrared spectroscopic technique is used to know the bonding in the ferrite sample. Metal-Oxygen (Mg-O &amp; Fe-O) and metal-metal (Mg-Fe) bonding is observed in the spectrum.</p> <p>&nbsp;</p> https://ultraphysicalsciences.org/paper/1069/ Microwave synthesis MgFe2O4, Oxalate nanoparticles.
