Abstract: Nanophase α-Fe2O3 particles were systhesized by a solid-phase method. The prepared samples were characterized by XRD, Mossbauer spectroscopy and TEM. The results show that the prepared samples are α-Fe2O3. The particle sizes of the samples are about 20-40nm and their shapes are peanut-like.

Key words: solid-phase synthesis, nanoparticles, α-Fe2O3
