MnZn ferrite material with high direct-current superposition characteristic and preparation method for MnZn ferrite material
The invention relates to a MnZn ferrite material with a high direct current superposition characteristic and a preparation method for the MnZn ferrite material, belonging to the technical field of ferrite materials. The MnZn ferrite material is composed of a main material and a dopant. The main material comprises the following oxides in molar percentage: 53.0-55.0 mol% of Fe2O3, 38.0-40.0 mol% of MnO, 0-1.5 mol% of NiO and the balance of ZnO; the dopant comprises the oxides in percentage by weight based on the pre-sintered main material: 0.02-0.20wt% of CaCO3, 0.001-0.10wt% of V2O5, 0.001-0.06wt% of Bi2O3, 0.01-0.40wt% of Co2O3, 0.01-0.09wt% of ZrO2 and 0.01-0.20wt% of GeO2. The material provided by the invention has the advantages of low high-temperature loss, high direct-current superposition characteristic, high Curie temperature, wide temperature range and high Bs.
