| Abstract | ||
| Hematite nanoparticles (α-Fe2O3) have been successfully fabricated by using auto-combustion method followed by calcination at 600 oC for one hour. The synthesized iron oxide nanoparticles were characterized by different tools such as Xray powder diffraction (XRD), Field-emission scanning electron microscope (FE-SEM) and Fourier transform infrared analysis (FT-IR). The average crystallite size of the as-fabricated iron oxide was calculated to be 54 nm. The characteristic absorption peaks at 535 and 450 cm-1 correspond to iron-oxygen stretching and bending vibration mode of α-Fe2O3, respectively. The FE-SEM photograph displayed that the synthesized hematite nanoparticles are agglomerated in quasi- spherical shapes with hard agglomeration and the average particle size in the range 1 µm | ||
