| titleOfInvention | Microwave ferrite material and preparation method and application thereof |
| abstract | The invention provides a microwave ferrite material and a preparation method and application thereof, wherein the preparation method comprises the following steps: (1) taking transition metal oxide, and performing primary ball milling, primary drying, primary sieving and presintering on the transition metal oxide to obtain a half-step ferrite; (2) performing secondary ball milling on the half-step ferrite obtained in the step (1), and performing secondary drying, secondary screening, granulation, molding and sintering to obtain the microwave ferrite material; wherein, the transition metal oxide in the step (1) comprises yttrium oxide, calcium oxide, ferric oxide, vanadium oxide, aluminum oxide and zirconium oxide. The invention provides a preparation method of ferrite for a miniaturized lumped parameter circulator, which enables the bandwidth of the miniaturized lumped parameter circulator working at 3.4-3.8GHz to reach 400MHz and the out-of-band resonance point to exceed 200 MHz. |
