Abstract

Procédé de préparation d'une composition de poudre de tantale qui consiste à : traiter thermiquement une poudre de tantale en flocons entre 1250 degrés C et 1550 degrés C pendant 5 à 120 minutes afin de pré-agglomérer la poudre en flocons; mélanger la poudre pré-aggomérée de tantale en flocons avec une poudre de tantale en granulés pour former une composition de poudre de tantale; agglomérer ladite composition de poudre de tantale de 1250 degrés C à 1550 degrés C pendant 5 à 120 minutes. La composition est utilisée pour des condensateurs solides au tantale.
