YIG ferrite substrate, preparation method thereof and microstrip circulator/isolator
The invention relates to the technical field of electronic materials, in particular to a microwave gyromagnetic YIG ferrite substrate, a preparation method of the microwave gyromagnetic YIG ferrite substrate and a microstrip circulator/isolator. The preparation method comprises the following steps: S1, obtaining powder of gyromagnetic YIG ferrite; s2, after the powder is prepared into tape casting slurry, tape casting is carried out, and a tape casting diaphragm is obtained; s3, punching and laminating the casting membrane, and pre-pressing to form a raw ceramic block; s4, pressing the pre-pressed green china block to form a compact green china block; and S5, carrying out cutting, glue discharging and sintering on the compact raw ceramic block to obtain the microwave gyromagnetic YIG ferrite substrate. According to the preparation method provided by the invention, excess materials generated in the punching and cutting processes can be recycled, so that the production and development cost is effectively reduced.
本发明涉及电子材料技术领域,特别涉及一微波旋磁YIG铁氧体基片及其制备方法、微带环形器/隔离器。其中,所述制备方法包括如下步骤:S1、获得旋磁YIG铁氧体的粉料;S2、将所述粉料制成流延浆料后进行流延,获得流延膜片;S3、对所述流延膜片进行打孔和叠片,预压形成生瓷巴块;S4、对所述预压生瓷巴块通过压制形成致密生瓷巴块;S5、对所述致密生瓷巴块进行切割、排胶和烧结,获得微波旋磁YIG铁氧体基片。本发明所提供的制备方法可实现对打孔、切割过程中所产生的余料进行回收,从而有效降低生产开发成本。
