| Abstract: | CoFe2O4/SiO2 nano-composites were prepared by the sol-gel method.The influence of drying temperature on the microstructure and crystalline size of CoFe2O4/SiO2 nano-composites were investigated by TG/DTA and XRD.Furthermore,the influence of the initial drying temperature on particle size of CoFe2O4 suggests that a well-established silica network provides more restriction on the growth of CoFe2O4 particles. |
