Manganese zinc ferrite wet pre-sintering process
The invention discloses a wet pre-sintering process of manganese zinc ferrite. The wet pre-sintering process comprises the following steps: wet-mixing ferrite powder containing Mn, Zn and Fe with an additive, and pre-sintering; the additive contains any one of an organic solvent, an organic acid and an organic binder; the mass ratio of the ferrite powder to the organic solvent to the organic acid to the organic binder to the adhesive is 1: (1-3): (0.1-0.4): (0.1-0.3): (0.05-0.09). According to the pre-sintering process, the problem that the soft magnetic ferrite is extremely easy to crack in the forming process can be solved, the magnetic conductivity and the magnetic flux density are improved, and the coercive force is reduced.
本发明公开了一种锰锌铁氧体湿法预烧工艺，包括以下步骤：将含有Mn、Zn、Fe的铁氧体粉末与添加剂湿式混合后预烧；所述添加剂含有有机溶剂、有机酸、有机粘结剂中的任意一种；所述铁氧体粉末：有机溶剂、有机酸、有机粘结剂、胶合剂的质量比为1:(1～3):(0.1～0.4):(0.1～0.3)：(0.05～0.09)。本发明预烧工艺不仅能够解决软磁铁氧体在成型工序中极其容易产生开裂的问题，还提升了磁导率、磁通密度，降低了矫顽力。
