用超级精矿粉替代铁鳞制备高性能烧结永磁铁氧体

Mass-Production of High Performance Sintered Permanent Ferrite Using Refined Magnetite Powders in Place of Millscale

阐述了用超级精矿粉替代铁鳞生产永磁铁氧体的必要性,介绍了超级精矿粉的制备技术,以及工业大生产选用不同来源的超级精矿粉制备高性能烧结永磁铁氧体的关键工艺技术。

It is necessary to mass-produce sintered permanent ferrite using refined magnetite powders in place of millscale as a result of supply shortage of the later. The preparing process of refined magnetite powders is introduced. The key technology for mass-producing high performance permanent ferrite using refined magnetite powders of different sources is described.
