Material for laminated high-frequency inductor and preparation method thereof
The invention discloses a material for a laminated high-frequency inductor and a preparation method of the material, and belongs to the technical field of electronic ceramic materials and preparation of the electronic ceramic materials. The material is prepared by compounding hexagonal system Co2Z ferrite magnetic powder and microcrystalline glass powder according to the mass percent of (30-60): (40-70). The method comprises the following steps: sintering, compacting and ball-milling and refining at high temperature, and then compounding with microcrystalline glass. In the sintering process, solid-phase reaction is not needed, and the glass ceramic and the glass ceramic can be fully compacted to form a complex of ceramic and glass after being subjected to heat preservation at 800-900 DEG C for 15-60 min together with the glass ceramic. The magnetic conductivity of the composite material is improved by 1.8-3.5 times, and the cut-off frequency can also reach 5-10 GHz. In other words, under the same structure, size and working frequency band, the inductance value of the high-frequency inductor can be remarkably improved.
本发明公开了一种叠层高频电感用材料及其制备方法，属于电子陶瓷材料及其制备技术领域，材料通过将六角晶系的Co2Z铁氧体磁粉与微晶玻璃粉按照质量百分比30～60:40～70复合而成；通过先将其在高温烧结致密并球磨细化以后，再跟微晶玻璃进行复合，让微晶玻璃均匀包覆磁粉，烧结过程中勿需再发生固相反应，只需要跟微晶玻璃一起在800～900℃保温15min～60min后能充分致密形成陶瓷‑玻璃的复合体即可，复合材料磁导率能提升1.8～3.5倍，截止频率也能达到5～10GHz，也即意味着在相同的结构、尺寸以及工作频段下，能显著的提升高频电感的电感量。
