Magnet core of Li-Zn-Mn ferrite. |
| 摘要 |
<p>In order to obtain a soft magnetic ferrite which is suitable in particular for use as an annular core in deflection yokes for T.V. and which excels by a high electric resistance and low power losses, Bi2O3 and V2O5 are added to an Li-Zn-Mn ferrite of the composition: (Li0.5Fe0.5)1-Z Znz Mny<II> Mnx<III> Fe2-x+ delta O4+3/2 delta + epsilon with 0.45 </= z </=0.62 0.01 </= x+y </= 0.25 -0.35 </= delta </= +0.05 -0.5 x </= epsilon The quantities of Bi2O3 and V2O5 are from 0.1 to 1% by weight, but together are never more than 1.2% by weight.</p> |
