中文摘要	Cobalt bearing magnetite particles were synthesized by aerial oxidation of ferrous and cobalt ions at alkaline condition and room temperature. The samples obtained at different intervals during reaction were characterized by XRD and IR. The cobalt-bearing ferrites were produced through the green-rust intermediate phase. Different compounds were synthesized by using Co2+/Fe3+ starting ratios of 1/20, 1/15, 1/10, 1/7, 1/5 and 1/3, and Co-ferrites with Co/Fe ratios of 0.05,0.06,0.08, 0.12, 0.17, 0.18 were obtained. The chemical composition and microstructure of those precipitates were characterized by chemical analysis and XRD. Meanwhile, further information of the producing process was confirmed by Mossbauer analysis. The results reveal that in the conditions of room temperature Co2+ will replace Fe3+ at octahedral positions in the spinel structure, and the increase of Co in initial solution is disadvantageous to the formation of the spinel structure. The non-magnetic ferric oxide is included in the compound containing Co outside the green-rust system.
