| titleOfInvention | Preparation method of ferrite magnetic material of core-shell structure |
| abstract | The invention relates to a preparation method of a ferrite magnetic material of a core-shell structure. The method comprises the following steps: (1) preparing hydrophilic ferroferric oxide particles; (2) preparing acetylated ferroferric oxide particles; and (3) preparing the ferrite magnetic material of the Fe3O4-SiO2 core-shell structure. According to the ferrite magnetic material of the core-shell structure, the acetylated ferroferric oxide is taken as a magnetic granular material to improve the magnetic property, and the core-shell structure with the silicon dioxide outside and the ferroferric oxide inside is formed by use of a specific process, so that the corrosion resistance of the material is greatly improved. As a result, the ferrite magnetic material has relatively high specific saturation magnetization and also is capable of well adapting to the corrosive environments. |
