Inductor sintering material with high magnetic conductivity
The invention discloses an inductor sintering material with high magnetic conductivity in the technical field of inductor sintering materials. A preparation process of the inductor sintering material comprises the following steps: S1, preparing a LiMn6Sn6 single crystal material; s2, primary ball milling; s3, pre-sintering is carried out; s4, secondary ball milling; s5, performing granulation; and S6, secondary sintering. The LiMn6Sn6 single crystal material is introduced, ferromagnetic coupling between Mn3 layers and magnetic coupling between Sn2Li and Mn3 layers are promoted through super-exchange interaction, the long-range ferromagnetic ordered state of the sintered material is enhanced, and the magnetic conductivity of the material is remarkably improved; the doping of the LiMn6Sn6 single crystal material promotes the growth of crystal grains in the sintered material through a grain boundary phase, so that the crystal structure is more compact, the overall density is improved, the microstructure of the material is optimized, and the eddy current loss is reduced; possible agglomerates are effectively scattered through secondary ball milling, the specific surface area of the powder is increased, sodium bismuthate and sodium molybdate with low melting points are added, the compactness of the sintered material is improved, and the overall performance of the material is further improved.
本发明公开了电感器烧结材料技术领域的一种高磁导率的电感器烧结材料，其制备过程包括如下步骤：S1、制备LiMn6Sn6单晶材料；S2、一次球磨；S3、预烧结；S4、二次球磨；S5、造粒；S6、二次烧结。本发明通过引入LiMn6Sn6单晶材料，通过超交换相互作用促进Mn3层间的铁磁耦合以及Sn2Li与Mn3层间的磁耦合，增强了烧结材料的长程铁磁有序状态，显著提高了材料的磁导率；LiMn6Sn6单晶材料的掺杂通过晶界相促进了烧结材料中晶粒的生长，使晶体结构更为致密，提高了整体密度，优化了材料的微观结构，减少了涡流损耗；通过二次球磨有效打散了可能形成的团聚体，增加了粉末的比表面积，加入了熔点较低的铋酸钠和钼酸钠，有助于提高烧结材料的致密度，进一步提升了材料的整体性能。
