摘要：
The invention relates to a sintered moulding of Li(Ni)Zn ferrite material, a transformer core and an inductor core of this material as well as several applications of these cores. In accordance with the invention, the majority of the grains of the sintered material have a monodomain structure. This leads to a substantial reduction of the loss factor and the overall losses when these mouldings are subjected to high-frequency applications and power applications. The ferrite material preferably comprises 59-65 mol% Fe2O3, 7-11 mol% Li2CO3, 4-8 mol% MnO and 20-28 mol% ZnO. This also provides the material with a high saturation magnetization.
摘要（中）：
本发明涉及这种材料的Li（Ni）Zn铁氧体材料，变压器芯和电感器芯的烧结成型，以及这些芯的几种应用。 根据本发明，烧结材料的大部分晶粒具有单畴结构。 当这些模制品经受高频应用和电力应用时，这导致损耗因子和总体损耗的显着降低。 铁氧体材料优选包含59-65mol％Fe 2 O 3，7-11mol％Li 2 CO 3，4-8mol％MnO和20-28mol％ZnO。 这也为材料提供了高饱和磁化强度。
