This paper reported a silica film was coated onto the surface of felTiferous oxide nano - particles with the methods of sol - gel. Composite particles with uniform diameter and relatively magnetism were prepared by controlling reaction conditions. The prepared composite particle were characterized by TEM , XRD and IR. The size of nano- composite particles is about 15 nm- 20 nm , their decentralization is favorable.
