NiZn series ferrite wave-absorbing material core and manufacturing method thereof
The invention discloses a NiZn series ferrite wave-absorbing material core and a manufacturing method thereof. The core comprises main components and additives; the main components comprise 64-70 wt% of Fe2O3, 15-25 wt% of ZnO and 6-21 wt% of NiO, and the total weight percentage of the content of the main components is 100 %; tantalum oxides and/or niobium oxides are adopted as the additives. According to the NiZn series ferrite wave-absoring material core and the manufacturing method thereof, the resistance value of the manufactured NiZn series ferrite core is improved by more than 15% at 25 MHz; the initial permeability is more than 3000, and a good filter effect on noise electromagnetic wave below 1MHz is achieved; not only are the properties of the wave-absorbing material core improved, but also the frequency range of noise electromagnetic wave absorbing is widened.
