چکیده انگلیسی
Hollow glass microspheres–CoFe2O4 (HGMs-CF) core-shell particles were successfully synthesized directly by using the homogeneous coprecipitation method at 90 °C without calcination. The morphology, composition, microstructure and the magnetic property of the samples were characterized by SEM, XRD, EDX and VSM, respectively. The results showed that the HGMs-CF core-shell particles exhibited smooth, compact and continuous CoFe2O4 coating on the surface of the HGMs. The Fe/Co atom ratio of the CoFe2O4 coating was 2.2, saturation magnetization (Ms) and coercivity (Hc) of the samples were 46 emu/g and 612 Oe, respectively. It was suggested that this method could be applied to the scale industry production for high purity products.
