摘要：
The oxidation products of Fe(OH)(2) formed in the presence of Co2+, Cu2+ and Cr3+ were characterized by various means. Co2+ and Cu2+ produced pure Fe3O4 by inhibiting the generation of alpha-FeOOH, whilst Cr3+ promoted the alpha-FeOOH formation and interfered with the Fe3O4 formation. The Fe3O4 particles produced with Co2+ exhibited high Fe2+ content, electrical conductivity and stability to oxidation. Mossbauer spectroscopy demonstrated that the excess Fe2+ replaced for Fe3+ in B-sites of Fe3O4. A small quantity of metal Fe formed in addition to Fe3O4 on adding Co2+. (C) 1999 Elsevier Science Ltd.
