一种镍锌软磁铁氧体及其制备方法
摘要：
本发明提供了一种镍锌软磁铁氧体，包括主成分和辅助成分，所述主成分包括Fe2O3、NiO、ZnO和CuO，辅助成分包括Al2O3、V2O5和CaO；所述主成分中Fe2O3的含量为51～52mol%，NiO的含量为14.5～16mol%，ZnO的含量为15～18mol%，CuO的含量为14～18mol%。本发明通过对镍锌铁氧体各组分含量进行优化，并采用流延工艺成型坯片，烧结后制成厚度小于0.2mm的磁片，使磁片在厚度较薄的情况下仍可使天线模块具有较高的通讯距离。
摘要（英）：

The invention provides a nickel-zinc soft magnetic ferrite, comprising principal components and auxiliary components, wherein the principal components comprise Fe2O3, NiO, ZnO and CuO; the auxiliary components comprise Al2O3, V2O5 and CaO; in the principal components, the content of Fe2O3 ranges from 51mol% to 52mol%, the content of NiO ranges from 14.5mol% to 16mol%, the content of ZnO ranges from 5mol% to 18mol% and the content of CuO ranges from 14mol% to 18mol%. According to the invention, the content of each component of the nickel-zinc ferrite is optimized, a blank is formed through casting process technology and then sintered to form a magnetic piece which is 0.2 mm thick, and the magnetic piece causes an antenna module to have a long communication distance under the condition of low thickness.
