| Abstract: | The nanocrystalline NiFe2O4 precursor was prepared by ultrasound-assisted coprecipitation in the presence of surfactant dodecyl benzene at room temperature,then the nanocrystalline NiFe2O4 with inverse spinel structure was obtained by calcining the precursor.The precursor and its calcined products were characterized by using XRD,FTIR,VSM,DLS and Zeta.The results showed that,the average grain diameter and average dispersive particle diameter of nanocrystalline NiFe2O4 precursor were 15nm and 45nm,respectivel... |
