NiZn ferrite and preparation method thereof
The invention discloses NiZn ferrite, which is prepared from the following raw materials in terms of oxide: 45-55 mol% of Fe2O3, 5-20 mol% of ZnO and the balance of NiO. The invention also discloses a method for preparing the NiZn ferrite by using a spark plasma sintering system, wherein the sintering temperature can be reduced to 900 DEG C, the heat preservation time is not needed, the time of a sample at a high temperature (greater than or equal to 600 DEG C) is less than or equal to 90 seconds, the time of sintering the sample is greatly reduced, the low-temperature and rapid sintering of the NiZn ferrite can be realized, the energy consumption can be greatly reduced, the experimental procedures are few, the operation is simple, and the prepared NiZn ferrite is compact and excellent in magnetic performance.
本发明公开了一种NiZn铁氧体，以氧化物计算，其原料包括：45‑55mol％的Fe2O3和5‑20mol％的ZnO，余量为NiO。本发明还公开了利用放电等离子体烧结系统制备NiZn铁氧体的方法，烧结温度可以降低至900℃，并且不需要保温时间，样品处于高温(≥600℃)的时间≤90s，大大降低了烧结样品的时间，不仅能够实现NiZn铁氧体的低温、快速烧结，同时也可以大大降低能耗，而且实验工序少，操作简单，制备的NiZn铁氧体致密且磁性能优良。
