Article Preview

We report on a novel method for preparation of high purity Sm2Fe17 phase by removing the liquid impurity phase from the Sm-rich precursor at high temperatures. With decreasing Sm addition, the percentage of liquid phase left as impurity is decreasing. Nitrogen absorption to the Sm2Fe17 powders results in a complete formation of Sm2Fe17N3, which shows a weak disproportionation reaction at 773 K. The magnetic performance of the Sm2Fe17N3 from precursors with different Sm content is improving with decreasing Sm content.
