Fabrication of Z-type barium ferrite/silica composites with enhanced microwave absorption
The Z-type barium ferrite/silica composites (Z-BCF/SiO2) were fabricated by in situ chemical synthesis method. The composition, structure, morphology and magnetic behavior of the composites were characterized by chemical analysis, IR, XRD, SEM, TEM and VSM. The results indicated that there were some...

description | The Z-type barium ferrite/silica composites (Z-BCF/SiO2) were fabricated by in situ chemical synthesis method. The composition, structure, morphology and magnetic behavior of the composites were characterized by chemical analysis, IR, XRD, SEM, TEM and VSM. The results indicated that there were some interactions between two components in the Z-BCF/SiO2 composites due to the coating of SiO2 on the Z-BCF particles. The magnetic properties of the Z-BCF/SiO2 composites were evidently less than that of the Z-BCF, owing to the small volume fraction of magnetic components in the samples. Due to the good transmission and loss properties on electromagnetic waves, the composites were better at microwave absorption than the parent component. Therefore, this research laid a foundation for the fabrication of highly efficient microwave absorbing material with enhanced wave impedance matching. |
