Resumé

The present paper describes a simple method of nanosized BiFeO3 by the solution combustion synthesis using bismuth and iron nitrates as oxidizers and the combination fuel of citric acid and ammonium nitrate, with fuel to oxidizer ratio (Ψ = 1) one. The average crystallite size of BiFeO3 nanoparticles was estimated from the full width half maximum of the X-ray diffraction peaks of powders using Scherrer’s formula. The ferroelectric transition of the sample at 8310C was detected by differential thermal analysis. Elemental analysis was done using Energy Dispersive X-Ray Analysis (EDX). Fourier Transform Infrared spectroscopy confirms the ferrite bond formation. Thermal analysis was done by Thermal gravimetric-Differential thermal analyzer and obtained results were presented in this paper. Keywords:  Solution Combustion Synthesis, X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Thermal gravimetric-Differential thermal analysis (TG-DTA), Fourier Transform Infrared Spectroscopy (FTIR)
