| Abstract: | Nanocrystalline oxide compound Ba(Zn1- xCox)2Fe16O27 has been synt hesized using PEG gel method. The products are characterized by means of X- ray powder diffraction analysis. Based on a two- layer structure, the Ba(Zn1- xCo x)2Fe16O27 powder is integrated with the traditional microwave absorbing materia l, iron particle, to form the absorbing coatings. The experimental result in dicates that the composite materials have a good absorbing property. The absorpt ive mechanism of nanocrystalline material has also been discussed. |
| Keywords: | Microwave absorption Composite material Barium ferrite Nanocryst al |
