Preparation method of manganese zinc ferrite magnetic spacer
The invention relates to the technical field of manganese zinc ferrite magnetic materials, in particular to a preparation method of a manganese zinc ferrite magnetic spacer. The preparation method comprises the following steps: sequentially carrying out ball milling treatment on manganese zinc ferrite powder, then mixing with a binder, and sequentially carrying out banburying, crushing, injection molding, catalytic degreasing and densification sintering to obtain the manganese zinc ferrite magnetic spacer. According to the preparation method, a metal injection molding process is introduced into the molding of the manganese-zinc ferrite magnetic spacer, so that the problems of material shortage, sintering deformation, cracking and the like caused by traditional pressing molding are solved, the manganese-zinc ferrite magnetic spacer with uniform sintering crystal grains and relatively low porosity is obtained, and the product yield is improved.
本发明涉及锰锌铁氧体磁性材料技术领域，尤其涉及一种锰锌铁氧体磁隔片的制备方法。该制备方法，将锰锌铁氧体粉末依次进行球磨处理，再与粘结剂混合，依次进行密炼、破碎、注射成形、催化脱脂和致密化烧结，得到锰锌铁氧体磁隔片。该制备方法将金属注射成形工艺引入到锰锌铁氧体磁隔片的成形当中，解决因传统压制成形所引起的缺料，烧结变形及开裂等问题，得到烧结晶粒均匀，孔隙率较低的锰锌铁氧体磁隔片，提高产品良率。
