| Abstract: | The Y-type barium ferrite Ba 2Co 2Fe 12O 22 particles were synthesized by citrate sol-gel method. The particles' crystallization processes were investigated by TG-DSC and IR methods.X-ray diffraction (XRD) and transmission electron microscope (TEM) showed the component and the widely distributed micrometer particles.The good dielectric and magnetic properties in high frequency band were also showed. |
