Manganese zinc ferrite magnetic core and preparation method thereof
The invention discloses a manganese zinc ferrite magnetic core which comprises the following components in percentage by mole: 45 mol%-55 mol% of ferric oxide, 32 mol%-39 mol% of manganese oxide, 8 mol%-21 mol% of zinc oxide, 0.20 mol%-0.45 mol% of a stabilizer and 0.15 mol%-0.32 mol% of a surfactant. The stabilizer is a mixture of silicon dioxide, cobalt oxide, titanium oxide and lead oxide. The stabilizer is prepared from the following components in percentage by mole: 0.03 mol%-0.25 mol% of silicon dioxide, 0.06 mol%-0.13 mol% of cobalt oxide, 0.03 mol%-0.05 mol% of titanium oxide and 0.01 mol%-0.03 mol% of lead oxide. The surfactant is one or a mixture of more of acrylic resin emulsion, polyvinyl alcohol, polyether, n-butyl alcohol and ammonium citrate. Corresponding materials are added to the manganese-zinc ferrite magnetic core, so that the stability of the manganese-zinc ferrite magnetic core in the using process is remarkably improved, the adverse effects of external temperature, humidity and other factors on the magnetic conductivity of the manganese-zinc ferrite magnetic core are greatly reduced, the reliability of the manganese-zinc ferrite magnetic core in the using process is improved, and the application requirements of high-power devices can be met.
