Preparation method of oriented ferrite magnetic shielding material
The invention discloses a preparation method of an oriented ferrite magnetic shielding material, which comprises the preparation of ferrite with various components and comprises the following steps: (1) preparing ferrite precursor powder by adopting a hydrothermal method; (2) putting the ferrite precursor powder obtained in the step (1) into a crucible, plugging the crucible into a tubular furnace, and heating for heat treatment; (3) after the reaction, cooling to room temperature, and taking out the crucible to obtain ferrite powder; (4) forming the synthesized ferrite powder to obtain ferrite; and (5) orienting the ferrite to obtain the oriented ferrite. The method is simple in process step, easy to operate, low in equipment requirement and safe and controllable in process, ferrite has magnetic noise and good magnetic shielding effect, and the sensitivity of a protected instrument is improved.
