Abstract

L'invention concerne un procédé de fabrication de poudres contenant des agents auxiliaires de compression, notamment des poudres métalliques. Le procédé selon l'invention consiste à mélanger un agent auxiliaire de compression pulvérulent avec une poudre initiale à une température située en dessous du point de fusion de l'agent auxiliaire de compression, et à chauffer le mélange ainsi obtenu à une température correspondant au moins à la température de fusion de l'agent auxiliaire de compression, ledit mélange ne subissant aucun mouvement lors du chauffage et du refroidissement successif. L'invention concerne également un procédé de fabrication de corps moulés métalliques frittables à partir de ces poudres contenant des agents auxiliaires de compression.
