Cubic and ellipsoide ultrafine monodispersed hematite colloidal particles wereprepared by hydrothermal reaction from Fe(OH)_3 get in the presence of Sn4+ ions. Thenumbers of nuclei increase with the concentration of Sn4+ ions. The initial concentrationof Fe(OH)_3 gel might approach to 0.5 mol.L- 1. The products were characterized by TEMand XRD.
