MnZn ferrite material with high saturation magnetic flux density and preparation method thereof
The invention discloses a MnZn ferrite material with high saturation magnetic flux density. The MnZn ferrite material consists of main components and auxiliary components, wherein the main components comprise the following parts calculated based on oxides: 50-55mol% of Fe2O3, 5-10mol% of ZnO and the balance of MnO; and the auxiliary components comprise the following parts according to the weight ratios in the total weight of the main components: 100-300ppm of SiO2, 150-1000ppm of CaCO3, 50-500ppm of Ta2O5, 50-350ppm of HfO2 and 200-5000ppm of SnO2. The invention realizes a ferrite magnetic core prepared from the MnZn ferrite material, wherein the saturation magnetic flux density at 100 DEG C is more than 430mT under the measurement condition of 1200A/m and 50Hz, and the power consumption of volume (Pcv) is less than 350kW/m<3> under the measurement condition of 100kHz and 200mT.
