Abstract:

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

Key words: α-Fe2O3, Monodispersed particle, Preparation
