Abstract

Selon la présente invention, on transforme une poudre précurseur comprenant un composé métallique en un échantillon destiné à l'électroréduction, par exemple par coulage en barbotine. On immerge ensuite l'échantillon dans un bain comprenant un sel fondu et on applique un potentiel cathodique afin d'enlever l'espèce non métallique de la poudre précurseur par électroréduction et dissolution dans le bain. Ceci permet généralement de former un échantillon métallique que l'on peut fragmenter pour former une poudre métallique. Dans un second aspect, l'invention concerne une matière d'alimentation en poudre que l'on transforme en un précurseur formé et l'on procède à une électroréduction plus longue afin d'obtenir un produit formé d'une grande précision dimensionnelle.
