High-frequency low-power-consumption manganese-zinc ferrite material and preparation method thereof
The invention relates to the technical field of ferrite material preparation, in particular to a high-frequency low-power-consumption manganese-zinc ferrite material and a preparation method thereof.The material comprises main raw materials and additives, wherein the main raw materials comprise the following components in percentage by mole: 53.5 to 56.5 mol% of Fe2O3, 40.5 to 42.5 mol% of Mn3O4and the balance being ZnO; the additives are calculated according to the weight percentage of the main raw materials; the additives comprise: 1000-1500 ppm of CaO, 100-300 ppm of SiO2, 1000-3000 ppm of TiO2, 2500-4000 ppm of Co3O4, 100-500 ppm of ZrO2, 200-400 ppm of Nb2O5, 1000-2000 ppm of NiO. According to the high-frequency low-power-consumption manganese-zinc ferrite material prepared by adopting the formula and the process disclosed by the invention, the power consumption at 100 DEG C is only 150KW/m<3> under the test conditions of 1MHz and 50mT, meanwhile, the high-frequency low-power-consumption manganese-zinc ferrite material also has relatively high sintering Bs reaching 500mT (25 DEG C) and 410mT (100 DEG C); and moreover, the adopted unique sintering process ensures that the product has lower high-frequency power consumption and higher sintering density.
