Auto-combustion Preparation and Characterization of BaFe2O4 Nanostructures by Using Lemon Juice as Fuel

In this work, barium monoferrite nanoparticles have been successfully synthesized via a simple sol-gel auto-combustion method. The synthesis was based on the reaction between Ba(NO3)2 andFe(NO3)3 in aqueous medium, in present of lemon juice as surfactant and fuel agent. The products were characterized by X-ray diffraction, scanning electron microscopy, and photo luminescence techniques. Effects of lemon juice amount and the temperature have been investigated to achieve an optimal condition. It was found that the phase and morphology of products could be seriously influenced by these parameters. Vibrating sample magnetometer (VSM) was used to study the magnetism properties of BaFe2O4 samples.
