| Abstract: | This paper reported a silica film was coated onto the surface of ferriferous 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. |
