| Zusammenfassung: | This invention relates to iron-base soft magnetic particles with high non-oxidation used in magnetic rheological liquid and its preparation method, which utilizes TEOS hydrolytic condensation reaction to cover a layer of SiO2 film on the magnetic particle surface to prepare magnetic composite particles, which have good non-oxidation performance, acid corrosion resistance and rather high magnetic strength. |
