Abstract

The invention discloses a temperature rise resistant soft magnetic ferrite material with wide temperature range and low power consumption and a preparation method thereof. The material comprises a main ingredient and doping ingredients, wherein the doping ingredients account for 3% to 8% of the total mass of the main ingredient; the main ingredient is an iron-rich formula; and the doping ingredients comprise CaCO3, CaO, Nb2O5, SiO2, V2O5 and Co2O3. The main formula and effective doping are optimized, and a reasonable sintering forming process is adopted, on one hand, the soft magnetic ferritematerial has high saturation flux density and high permeability; on the other hand, the uniformity of grain size is controlled, the gas hole ratio is reduced, and the distribution of the ingredients inside the particles and among the particles is reduced, so that the microstructure of the soft magnetic ferrite is controlled more effectively; and the obtained product has excellent high-temperaturelow power consumption performance, so that the heating and machine burning phenomena of a transformer under high frequency can be avoided effectively.
