Wide-temperature broadband MnZn power ferrite material and preparation method thereof
The invention discloses a wide-temperature broadband MnZn power ferrite material, and relates to the technical field of ferrite material preparation. The wide-temperature broadband MnZn power ferrite material comprises main components and an additive, and is characterized in that the main components comprise 51.5 to 53.0 mol% of Fe2O3, 10.0 to 12.0 mol% of ZnO and the balance of MnO; the additive is prepared from the following components in percentage by weight: 0.02 to 0.08 weight percent of CaCO3, 0.01 to 0.05 weight percent of Nb2O5, 0.01 to 0.05 weight percent of ZrO2, 0.3 to 0.5 weight percent of Co2O3, 0.01 to 0.02 weight percent of NiO and 0.001 to 0.012 weight percent of BTO-based PTC (Positive Temperature Coefficient) dielectric ceramic powder on the basis of the weight of the pre-sintered main components. According to the invention, the stability of the magnetic conductivity is improved, and particularly, the loss in a wide temperature range of 25-140 DEG C and a wide frequency range of 100-300kHz is reduced at the same time.
