Abstract

La présente invention a consisté à inclure dans un mélange pulvérulent à base de fer des particules d'oxyde d'un diamètre particulaire moyen d'au moins 0,5 µm à raison de 0,01% à 5,0% en poids, ce qui a eu pour résultat d'augmenter la fluidité dudit mélange pulvérulent à base de fer, d'améliorer la densité de la poudre compactée dans le moule, et de permettre, d'une part une réduction considérable de la force d'éjection après formation de la poudre, et d'autre part la production de marchandises de meilleure qualité tout en réduisant les coûts de fabrication.
