        This paper compares the effect of using different types of iron powders for the preparation of 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, prepared from sponge and water atomized iron powders yield -magnets with a high degree of texture. However, after a suitable treatment with hydrogen followed by nitrogenation, -powders made from Carbonyl iron produce magnets with the best quality regarding coercivity, remanence and degree of texture.
