The iron oxide nanoparticles type hematite (α-Fe2O3) have been prepared by Sol-Gel technique using ferric nitrate and sodium bicarbonate as precursors. The products were annealing at (200, 300, 400 and 500°C) and characterized by X-ray diffraction (XRD), atomic force microscopy (AFM), surface morphology by scanning electron microscopy (SEM) and fourier transform infrared spectroscopy (FTIR) spectrum. The results showed that the product was α-Fe2O3 nanoparticles, and the increasing temperature was an important factor in the formation of α- Fe2O3 nanoparticles. The average grain size found to be (79.715 -11.311 nm) after annealing between (200 -500°C).
