Manganese zinc ferrite with low stress sensitivity and sintering method thereof
The invention provides a low-stress sensitive manganese zinc ferrite and a sintering method thereof. The sintering method comprises the following steps: (1) carrying out compression molding on manganese zinc ferrite powder to obtain a blank to be sintered; and (2) carrying out multi-stage sintering on the blank to be sintered, and then cooling to obtain the low-stress sensitive manganese zinc ferrite, wherein the multi-stage sintering process consists of first-stage sintering, second-stage sintering, third-stage sintering and fourth-stage sintering of which the temperatures are increased in a gradient manner. The manganese-zinc ferrite with low stress sensitivity, wide frequency, high impedance and high conductivity is prepared by adopting a multi-stage sintering mode of first-stage sintering, second-stage sintering, third-stage sintering and fourth-stage sintering with the temperature increased in a gradient manner, and the inductance drop proportion of the manganese-zinc ferrite is smaller than that of the traditional manganese-zinc ferrite under the condition that the manganese-zinc ferrite is subjected to the same stress.
本发明提供一种低应力敏感的锰锌铁氧体及其烧结方法。所述烧结方法包括以下步骤：(1)将锰锌铁氧体粉料压制成型，得到待烧结坯件；(2)将所述待烧结坯件进行多级烧结，然后进行降温，得到所述低应力敏感的锰锌铁氧体；其中，所述多级烧结的过程由温度呈梯度增加的一级烧结、二级烧结、三级烧结和四级烧结组成。本发明通过采用温度呈梯度增加的一级烧结、二级烧结、三级烧结和四级烧结的多级烧结方式，制备得到了一种低应力敏感、宽频高阻抗高导的锰锌铁氧体，其在在受到相同应力的情况下较传统锰锌铁氧体的电感跌落的比例较小。
