Because of aggregation and low chemical stability of nanomagnetic particles, we use Sol-Gel method as surface modification in this paper to improve the disperse ability and the chemical stability of Fe3O4particles. At first, Fe3O4were prepared by chemical-precipitation method. Then, the Sol-Gel method was used to modify the surface of the particles. Core-shell structural Fe3O4@ S iO2composite magnetic particles were prepared by hydrolysis and condensation of tetraethyl orthosilicate using Fe3O4nanomagnetic particles as seeds. XRD,VSM were applied to characterize the composite magnetic particles. The effects of rotational speed and the quantity of TEOS on the performance of Fe3O4@ S iO2composite magnetic particles were investigated.
