摘      要：The Z-type barium ferrite/silica composites(Z-BCF/SiO2)were fabricated by in situ chemical synthesis *** composition,structure,morphology and magnetic behavior of the composites were characterized by chemical analysis,IR,XRD,SEM,TEM and *** 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 *** 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 *** to the good transmission and loss properties on electromagnetic waves,the composites were better at microwave absorption than the parent ***,this research laid a foundation for the fabrication of highly efficient microwave absorbing material with enhanced wave impedance matching.
