Preparation process of wide-temperature manganese zinc ferrite material
The invention discloses a preparation process of a wide-temperature manganese-zinc ferrite material, the wide-temperature manganese-zinc ferrite material comprises main components and auxiliary components, the main components comprise, by mass, 65%-75% of ferric oxide, 10%-15% of manganous-manganic oxide and 10%-15% of zinc oxide, and the auxiliary components are selected from at least one of V2O5, Ca2O3, Nb2O5 and TiO2; the preparation process comprises the following steps: carrying out primary sanding on prepared raw materials to obtain slurry with the particle size of (0.8-1.2) mu m, drying the slurry, presintering, carrying out secondary sanding, adding polyvinyl alcohol into the obtained sanded material, stirring, carrying out spray granulation to prepare granules for molding, molding, pressing and sintering the granules. The wide-temperature manganese zinc ferrite material has the characteristic of wide-temperature stability, and the practical application cost can be reduced.
本发明公开了一种宽温锰锌铁氧体材料的制备工艺，宽温锰锌铁氧体材料的原料包括主成分及辅助成分，所述主成分以质量百分比计，包括65％～75％的三氧化二铁，10％～15％的四氧化三锰及10％～15％氧化锌，所述辅助成分选自V2O5、Ca2O3、Nb2O5、TiO2中的至少一种；制备工艺包括：将准备的原料进行一次砂磨后得到粒径为(0.8～1.2)μm的浆料，烘干浆料后进行预烧，然后进行二次砂磨，将得到的砂磨料，加入聚乙烯醇搅拌后进行喷雾造粒，制备为成型用颗粒料，颗粒料经成型压制后进行烧结。本发明宽温锰锌铁氧体材料具有宽温稳定性的特性，能够降低实际应用成本。
