Preparation method of honeycomb nickel-zinc ferrite material
The invention relates to the field of ferrite preparation, in particular to a preparation method of a honeycomb nickel-zinc ferrite material. The invention provides a preparation method of a honeycomb nickel-zinc ferrite material, which comprises the following steps: drying and calcining a solution containing nickel nitrate, zinc nitrate, ferric nitrate and polyvinylpyrrolidone to obtain the honeycomb nickel-zinc ferrite material, in a solution containing nickel nitrate, zinc nitrate, ferric nitrate and polyvinylpyrrolidone, the molar ratio of nickel to zinc to iron is x: (1-x): 2, and x is more than or equal to 0 and less than or equal to 1. The honeycomb-shaped nickel-zinc ferrite material prepared by the preparation method disclosed by the invention is fine and uniform in crystal grain and moderate in honeycomb size and wall thickness, and the obtained nickel-zinc ferrite material has excellent saturation magnetization and also has relatively good residual magnetization and coercive force.
本发明涉及铁氧体制备领域，具体涉及一种蜂窝状镍锌铁氧体材料的制备方法。本发明提供一种蜂窝状镍锌铁氧体材料的制备方法，包括如下步骤：将包含硝酸镍、硝酸锌、硝酸铁和聚乙烯吡咯烷酮的溶液烘干、煅烧，得到所述蜂窝状镍锌铁氧体材料；在包含硝酸镍、硝酸锌、硝酸铁和聚乙烯吡咯烷酮的溶液中，镍、锌和铁的摩尔比为x：(1‑x)：2，其中0≤x≤1。本发明制备得到的蜂窝状镍锌铁氧体材料，其晶粒细小均匀，蜂窝尺寸及壁厚大小适中，且所得到的镍锌铁氧体材料具有优异的饱和磁化强度，同时还具有较好的剩余磁化强度和矫顽力。
