Paper Title:
Sm2Fe17 Prepared by Calciothermic Reduction-Diffusion Using Different Iron Powders
  Abstract

This paper compares the effect of using different types of iron powders for the preparation of Sm2Fe17 by calciothermic reduction-diffusion (CRD). Three types of iron powder were used: carbonyl, sponge and water atomized. The results show that, when immediately nitrogenated after the CRD process, Sm2Fe17 prepared from sponge and water atomized iron powders yield Sm2Fe17N3-magnets with a high degree of texture. However, after a suitable treatment with hydrogen followed by nitrogenation, Sm2Fe17-powders made from Carbonyl iron produce magnets with the best quality regarding coercivity, remanence and degree of texture.
