Ultrahigh-frequency inductor ferrite core and preparation method thereof
The invention relates to the technical field of magnetic core preparation, and discloses an ultrahigh-frequency inductor ferrite magnetic core, which comprises the following raw materials in percentage by mass: 52% of ferric oxide (Fe2O3), 8-10% of zinc oxide (ZnO), and the balance of manganese oxide (Mn3O4) and trace additives, can be used in an ultra-wide temperature environment of 40-140 DEG Cand an ultra-high frequency environment of 100-500 KHz, and is ultra-low in the power loss. The invention also discloses a preparation method of the ferrite core of the ultrahigh frequency inductor, wherein the method comprises the following steps: injecting heated and melted ferrite granules into a die cavity at high pressure of 125-150kPa, and cooling and curing to obtain the circular ferrite core, and is suitable for batch production of ferrite cores with complex shapes. The problem that an existing dry pressing forming method cannot be suitable for batch production of ferrite cores in complex shapes is solved.
本发明涉及磁芯制备技术领域，且公开了一种超高频电感器铁氧体磁芯，包括以下物质的量百分比的原料：52%的氧化铁（Fe2O3）、8%～10%的氧化锌（ZnO），余量为氧化锰（Mn3O4)和微量添加剂；所述铁氧体磁芯可在（‑40～140）℃的超宽温、100KHz～500KHz的超高频环境下使用，并且其功率损耗超低。本发明还公开了一种超高频电感器铁氧体磁芯的制备方法，该制备方法将受热融化的铁氧体粒料在125kPa～150kPa的高压射入模腔，经冷却固化后，得到圆环铁氧体磁芯，该方法适用于形状复杂铁氧体磁芯的批量生产，解决了目前的干压成型法无法适用于形状复杂铁氧体磁芯的批量生产问题。
