Low-Cost Precursor for Synthesis of High Coercivity Fe-N Magnets |
摘要 |
The disclosure describes a method of producing iron nitride magnets using Zn-doped iron oxide precursors. The iron oxide precursors are reduced and nitrided to produce a powder containing iron nitride in the Fe16N2 phase. The inclusion of Zn in the iron oxide precursor enhances the magnetic properties of the iron nitride powder. |
