TITANIUM-CONTAINING AND COBALT-CONTAINING MANGANESE-ZINC FERRITE CORE AND METHOD OF MANUFACTURING SAME |
| 摘要 |
A ferromagnetic titanium-containing and cobalt-containing manganese-zinc-ferrite core which shows low power losses at high drive in a wide temperature range, characterized in that its composition essentially corresponds to the molecular formula Mna2+Znb2+Fec2+Cod2+Ti44+VcxFef3+O42- With Vc=cation vacancy concentration 0.65 </= a </= 0.80 0.10 </= b </= 0.25 0.07 </= c </= 0.10 0.005 </= d </= 0.007 0.02 </= e </= 0.04 0.003 </= x </= 0.010 1.92 </= f </= 1.98 a + b + c + d - e + 3x = 1; f + 2e - 2x = 2. |
