Yttrium iron garnet ferrite material and preparation method thereof
An yttrium iron garnet ferrite material and a preparation method thereof are disclosed. The chemical formula of the material is Y<3-x-y-z>GdxCayCuzFe<5-a-b-c>InaVbAlcO12. The preparation method mainlyincludes mixing ball milling; pre-firing; secondary ball milling; granulation molding; and sintering. The main advantages are that the prepared ferrite material has fine and uniform grains, which helps to obtain a dense microstructure, thereby improving the high-power endurance of the material; the material is suitable for the use of various high-power isolators in communication base stations; through Cu<2+> doping, the sintering temperature of the material is reduced properly, which is beneficial to material mass production.
本发明公开了一种钇铁石榴石铁氧体材料及其制备方法，其化学式为YGdCaCuFeInVAlO。所述钇铁石榴石铁氧体材料的制备方法，主要包括混料球磨；预烧；二次球磨；造粒成型；烧结。本发明的主要优点是制备的铁氧体材料晶粒细小且均匀，有助于获得致密的显微结构，从而提高材料高功率承受能力，适用于通讯基站各种高功率隔离器使用，同时通过Cu掺杂，适当降低了材料烧结温度，从而有利于材料批量化生产。
