High-frequency low-temperature-coefficient low-loss nickel-zinc ferrite and preparation method thereof
The invention discloses a high-frequency low-temperature-coefficient low-loss nickel-zinc ferrite and a preparation method thereof, and belongs to the field of ferrite soft magnetic materials, the chemical formula of the ferrite is Ni < 1-x > ZnxFe2O4, x is more than or equal to 0 and less than or equal to 0.5, one or two doping materials of Co2O3 or TiO2 are added during preparation, 0.3-0.9 wt% of Co2O3, 0.1-1wt% of TiO2, 0.1-1wt% of Fe2O3, 0.1-1wt% of Fe2O3, 0.1-1wt% of Fe2O3 and the balance of Fe. The specific temperature coefficient alpha [mu] r of the low-temperature-coefficient and low-loss nickel-zinc ferrite material provided by the invention is reduced to 1-8 from the current common 8-20, and the nickel-zinc ferrite material has extremely high magnetic conductivity frequency stability and relatively low loss in a wide temperature range of-55 to 120 DEG C, and the overall performance is far higher than the current industry level; and technical support is provided for production of high-reliability soft magnetic materials for electronic equipment devices in severe temperature environments.
