Abstract: Spherical and cubic monodispersed hematite colloidal particles (30, 40 and 65 nm) were prepared by forced hydrolysis of acidified solutions of FeCl3.The reaction system is dynamic and open to increase the relative motion speed between the solute ions and the nuclei.The shape and size of the particles depend on the experimental conditions.The particles were characterized by TEMand XRD.
