Abstract

La présente invention concerne de la poudre de fer réduit qui réduit les inclusions grossières, présente une excellente aptitude au moulage, une porosité élevée après le frittage, et une excellente réactivité par unité de masse, et qui peut être efficacement utilisée en tant que matériau de réaction, même dans les particules. La densité apparente de la poudre de fer réduit se situe dans la plage de 1,00 à 1,40 Mg/m3.
