| titleOfInvention | A kind of preparation method of the ferromagnetic core that contains modified carbonize aluminium |
| abstract | The preparation method that the invention discloses a kind of ferromagnetic core that contains modified carbonize aluminium, comprises the following steps: pre-burning compound: compound A component is Fe 2 O 3 , MnO, boron oxide, graphite, calcium oxide, modified carbonize aluminium and silicalite stone flour; Compound B is in the following ratio component that is equivalent to compound A gross weight: SnO 2 , chrome green, boron oxide, gallium oxide, Zr, Ba and Ag; Then, compacting green compact dry by grinding, mixed pulp, powder spraying and sintering process make successively; The present invention designs and sintering process by optimization of C/C composites, the initial permeability of the product of producing is 19500, after sintering, product cracking is few, qualification rate reaches more than 92.8%, have grain boundary resistance rate high, the porosity is low, crystal grain is large and uniform feature, and impedance operator is excellent in lower frequency range, every electromagnetic performance is stable, and magnetic core product is applicable to each electronic applications. |
