Nickel-zinc-copper ferrite as well as preparation method and application thereof
The invention relates to nickel-zinc-copper ferrite as well as a preparation method and application thereof. The nickel-zinc-copper ferrite comprises main components and auxiliary components, the main components are prepared from the following components in percentage by mole: 64 to 66.7 mol percent of Fe2O3, 9 to 12 mol percent of NiO, 13.5 to 19 mol percent of ZnO and 3 to 9.5 mol percent of CuO according to the total mole percent of 100 mol percent; based on the total mass percentage of the main components, the auxiliary components comprise 0.3 to 1.5 wt% of Bi2O3, 0.1 to 0.6 wt% of Co2O3, 0.03 to 0.08 wt% of CaCO3 and less than or equal to 0.1 wt% of ZrO2. By controlling the contents of Fe2O3, ZnO, NiO and CuO and adjusting the contents of the auxiliary components, the prepared nickel-zinc-copper ferrite has high saturation flux density, high magnetic conductivity, high Curie temperature, low residual magnetic flux density and low specific temperature coefficient, and can be better applied to power inductors or common-mode inductors.
本发明涉及一种镍锌铜铁氧体及其制备方法与应用，所述镍锌铜铁氧体包括主要成分与辅助成分；以总摩尔百分数为100mol％计，所述主要成分包括：Fe2O3 64‑66.7mol％，NiO 9‑12mol％，ZnO 13.5‑19mol％，CuO 3‑9.5mol％；以主要成分的总质量百分含量计，所述辅助成分包括：Bi2O3 0.3‑1.5wt％，Co2O30.1‑0.6wt％，CaCO3 0.03‑0.08wt％，ZrO2≤0.1wt％。本发明通过控制Fe2O3、ZnO、NiO和CuO的含量搭配辅助成分的含量调整，使得制得的镍锌铜铁氧体具有高饱和磁感应强度、高磁导率、高居里温度、低剩余磁感应强度以及低比温度系数，可以更好地应用于功率电感或共模电感中。
