Direct-current-superposition-resistant MnZn ferrite material as well as preparation method and application thereof
The invention relates to a direct current superposition-resistant MnZn ferrite material as well as a preparation method and application thereof. The direct current superposition-resistant MnZn ferrite material comprises a main material MnZn ferrite and an auxiliary material MnZn ferrite, the first additive comprises 0.3 wt% of Co2O3, 0.05 wt% of ZrO2, 0.03 wt% of V2O5 and 0.15 wt% of CaO according to the weight percentage of the main material and calculated by oxide, and the second additive comprises 0.1-0.5 wt% of YIG ferrite particles according to the weight percentage of the main material and calculated by oxide. The preparation method is an oxide ceramic method, and the green body is subjected to segmented sintering by controlling temperature and oxygen partial pressure conditions. According to the MnZn ferrite material disclosed by the invention, cobalt doping, YIG ferrite compounding and sintering process adjustment are performed, so that the MnZn ferrite material is good in morphology, high in magnetic conductivity and excellent in direct current superposition resistance.
