Abstract

The invention relates to the technical field of magnetic material preparation, in particular to a preparation method of a high-performance gyromagnet ferrite material. The preparation method includes:processing aloe to allow the aloe to grow a large number of root hairs, then using a metal salt solution to spray the aloe, using the root hairs of the aloe to enrich and absorb metal ions to obtainthe aloe root hairs rich in bismuth, zinc and aluminum ions, subjecting the aloe root hairs and rice husks rich in silicon to blending fermentation, using microorganisms to degrade the aloe root hairsand the rice husks, fermenting to obtain a fermentation product containing bismuth, zinc and aluminum ions and silicon, pre-sintering to obtain ferrite preform, blending the ferrite preform and the fermentation product, performing high-pressure compression molding, drying, and sintering under the sintering temperature of about 900 DEG C to obtain the high-performance gyromagnet ferrite material.The preparation method has the advantages that the prepared gyromagnet ferrite material is high in crystallinity degree, high in compactness, large in grain size, high in final saturation magnetization intensity, low in coercivity and promising in application prospect.

Description

technical field [0001] The invention relates to the technical field of magnetic material preparation, in particular to a method for preparing a high-performance gyromagnetic ferrite material. Background technique [0002] With the rapid development of electronic information technology, electronic circuits and related systems continue to develop in the direction of miniaturization, integration, high frequency and convenience, which proposes smaller size, higher operating frequency and more reliable electronic component modules. The temperature stability, higher integration and multi-functional development requirements. With the development of technology in today's electronics field, magnetic materials have been widely used. As large as engines, generators, transformers, drives, and medical instruments, as small as sensors, memories, and antennas, they are all inseparable from magnetic materials. [0003] Ferrite is a type of magnetic material. Its magnetism comes from the ...
