    Synthesis of α-Fe2O3 nanoparticles by dry high-energy ball

    Nov 25, 2016 In this research, hematite nanoparticles (α-Fe2O3 NPs) with spherical morphology were synthesized by high-energy ball-milling method for different milling times (40 and 60 h) at dry medium. The synthesized α-Fe2O3 NPs were characterized by X-ray diffraction and field-emission scanning electron microscope (FE-SEM) techniques. An average particle size (APS) of α-Fe2O3 NPs after 40

    Effect of Fe2O3 crystallite size on its mechanochemical

    Fe2O3 powders with different crystallite sizes prepared by heating FeOOH at various temperatures were ground with La2O3 powder using a planetary ball mill to investigate the effect of crystallite size on mechanochemical synthesis of LaFeO3. Fe2O3 powder with smaller crystallite size obtained by heating at lower temperature reacts more easily with La2O3 than that with larger size. The
