Abstract

L'invention concerne un procédé servant à la production d'une poudre métallique, consistant à introduire un métal brut de façon continue ou discontinue dans un four de chloruration, pour former une vapeur de chlorure métallique de façon continue, puis à faire réagir la vapeur de chlorure métallique avec un gaz hydrogène dans un four de réduction, pour produire la poudre métallique de façon continue. Le procédé se caractérise par le fait que le poids du four de chloruration est mesuré durant la réaction de chloruration et par le fait que l'introduction du métal brut dans le four est régulée sur la base des mesures réalisées.
