Broadband MnZn ferrite material with high magnetic conductivity
The invention provides a broadband MnZn ferrite material with high magnetic conductivity. The broadband MnZn ferrite material comprises the following main components: 51-53mol% of Fe2O3, 24-30mol% of MnO and 19-23mol% of ZnO; and on the basis of the main components, the broadband MnZn ferrite material is added with the following auxiliary components: 50-300ppm of CaO, 50-600ppm of MoO3, 50-800ppm of Sb2O3 and 50-300ppm of Nb2O5. Through a powder metallurgy process, the initial magnetic conductivity of the obtained standard toroidal core (specification is phi25mm*15mm*7mm) is greater than 12,000 under the frequency of 10kHz and is greater than 9,000 under 200kHz.
