Manganese-zinc ferrite material with wide temperature range and high magnetic permeability as well as preparation method and application of manganese-zinc ferrite material
The invention relates to the technical field of manganese zinc ferrite materials, in particular to a wide-temperature high-permeability manganese zinc ferrite material as well as a preparation method and application thereof. The invention discloses a wide-temperature high-permeability manganese zinc ferrite material, which comprises main components and additives, and the main components comprise the following raw materials in molar percentage: 53.17 to 53.4 percent of Fe2O3, 18.55 to 19.4 percent of ZnO, and 27.43 to 28.1 percent of MnO. The manganese-zinc ferrite material with the mu i of 10000 (1 +/-20%), the Curie temperature Tc of more than or equal to 160 DEG C and the mu imin of more than or equal to 8500 at the temperature of 20-120 DEG C is prepared, the problems that the valley point of the mu i-T curve of the existing manganese-zinc ferrite material with the mu i of 10000 with the Tc of more than or equal to 160 DEG C is relatively large and the temperature stability is relatively poor are solved, and meanwhile, the competitive advantages of the manganese-zinc ferrite material in severe use environments such as automotive electronics are improved.
