| titleOfInvention | Zirconium-doped barium ferrite wave-absorbing material and preparation method thereof |
| abstract | The invention discloses a zirconium-doped barium ferrite wave-absorbing material having a chemical formula of BaFe12-xZrxO19, wherein x is 0.3-0.5, zirconium-doped barium ferrite is a polycrystalline powder, and Fe<3+> and Fe<2+> exist in the barium ferrite simultaneously. A preparation method comprises the preparation steps: mixing barium nitrate, iron nitrate and zirconium nitrate, adding deionized water, and dissolving into a nitrate solution; placing EDTA in deionized water, and dissolving into an EDTA solution; adding the nitrate solution into the EDTA solution, heating, drying, and thus obtaining a dry gel; and sintering the dry gel to obtain a zirconium-doped barium ferrite powder, then grinding, and thus obtaining the zirconium-doped barium ferrite wave-absorbing material. The wave-absorbing material has the characteristics of thin matching thickness and wide wave-absorbing frequency band, can be used for a wave-absorbing coating layer, and can have wide applications in the electromagnetic shielding and stealth fields. |
