BaFe12O19/ZnO composites were fabricated in large scale via a simple solution method. The phase structures, morphologies, particle size, chemical compositions of the composites have been characterized by X-ray diffraction (XRD), field emission scanning electron microscope (FESEM). The test of microwave absorption was carried out by using the network analyzer Agilent HP-8722ES. The maximum microwave loss reaches 37.5 dB and bandwidth with the loss above 10 dB is about 4 GHz in the 13.7-18.0 GHz range which indicate that BaFe12O19/ZnO composites have potential applications as electromagnetic wave absorber.
