| titleOfInvention | A kind of preparation method of high frequency high resistivity Li-Zn soft magnetic ferrites |
| abstract | The present invention relates to a kind of preparation method of high frequency high resistivity Li-Zn soft magnetic ferrites.First the method by adding zinc sulfate and Lithium Acetate obtains dispersing and mixing liquid in copperas solution, then carries out hydrothermal crystallizing reaction in autoclave, obtained mixed powder; Finally obtained mixed powder and silicon sol are carried out grinding stirring, coldmoulding, carry out roasting sintering, obtained Li-Zn soft magnetic ferrites.The invention has the advantages that: 1) the present invention adds silane coupling agent and effectively can reduce particle aggregation, improve dispersiveness and the mobility of powder, improve the ferritic compact density of Li-Zn and homogeneity.2) Li-Zn ferrite of the present invention has good high-frequency soft magnetic characteristic and lower sintering temperature.3) the present invention adopts silicon sol as mineral binder bond, and in high-temperature sintering process, element silicon can play chanza, improves the ferritic magnetic property of Li-Zn, improves the ferritic microtexture of Li-Zn. |
