Secondary sintering method of MnZn power ferrite
The invention relates to a secondary sintering method of MnZn power ferrite, which comprises the following steps: (a) heating a MnZn ferrite product from room temperature to the highest holding temperature at the heating rate of 1-5 DEG C/min, and keeping the temperature at the highest holding temperature for 0.5-5 hours; the highest holding temperature is 1000-1330 DEG C, the oxygen concentration is controlled to be less than or equal to 0.75% during heating, and the oxygen concentration is controlled to be 0.05-7% during heat preservation at the highest holding temperature; and (b) cooling the MnZn ferrite product treated in the step (a) from the highest holding temperature to room temperature. Therefore, the loss of the material can be greatly reduced, and the loss characteristic meets the use requirement.
本发明涉及一种MnZn功率铁氧体二次烧结方法，包括以下步骤：(a)将MnZn铁氧体产品从室温以1～5℃/min的升温速率升温至最高保持温度，于所述最高保持温度保温0.5～5h；所述最高保持温度为1000～1330℃，升温时控制氧气浓度≤0.75％，于所述最高保持温度保温时控制氧气浓为0.05～7％；(b)将步骤(a)处理后的所述MnZn铁氧体产品由所述最高保持温度降温至室温即可。从而可以较大幅度降低材料的损耗，使损耗特性满足使用要求。
