Multi-element composite ferrite material as well as preparation method and application thereof
The invention provides a multi-element composite ferrite material as well as a preparation method and application thereof, and relates to the technical field of ferrite preparation. The preparation method of the multi-element composite ferrite material provided by the invention comprises the following steps: mixing Fe2O3, NiO, MgO, CuO and ZnO to obtain a mixed material; adding water into the mixture for pelletizing to obtain spheres; pre-sintering the ball body to obtain a pre-sintered body; the pre-sintering temperature ranges from 880 DEG C to 1050 DEG C; crushing the pre-sintered body to obtain a granular material; mixing the granular material with a binder, and granulating to obtain a binder-coated granular material; the particles coated with the binder are pressed, and a blank is obtained; and sintering the blank to obtain the multi-element composite ferrite material. The multi-element composite ferrite material prepared by the invention has a relatively low sintering temperature, can be co-fired with a conventional nickel-zinc material, and improves the performance of the magnesium-copper-zinc ferrite material at the same time.
本发明提供了一种多元复合铁氧体材料及其制备方法和应用，涉及铁氧体制备技术领域。本发明提供的多元复合铁氧体材料的制备方法，包括以下步骤：将Fe2O3、NiO、MgO、CuO和ZnO混合，得到混料；将所述混料进行加水造球，得到球体；将所述球体进行预烧，得到预烧体；所述预烧的温度为880～1050℃；将所述预烧体进行破碎，得到颗粒料；将所述颗粒料和粘结剂混合，进行造粒，得到粘结剂包覆的颗粒料；将所述粘结剂包覆的颗粒料进行压制，得到毛坯；将所述毛坯进行烧结，得到多元复合铁氧体材料。本发明制备的多元复合铁氧体材料具有较低的烧结温度，能够与常规镍锌材料共烧，同时提升了镁铜锌铁氧体材料的性能。
