Abstract :Barium titanate nanoparticles have been synthesized via Pechini method, using barium acetate and an aqueous solution of titanium(IV) triethanolaminato isopropoxide. Structural properties of barium titanate (BaTiO3) are characterized by X-ray diffraction (XRD), Rietveld refinement, scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDX), thermogravimetric analysis (TGA) and Fourier-transform infrared spectroscopy (FT-IR). XRD and Rietveld refinement studies revealed that BaTiO3 possesses a cubic structure with a space group of Pm-3m (#221). As estimated by the Scherrer formula, the average crystallite size was accurately determined to be properly 51.9 nm for the calcined temperature at 800ºC.
