Abstract

Διεργασία για την παραγωγή μορφοποιημένων προϊόντων μεταλλουργίας σε σκόνη Ta/Nb και/ή σκονών υδριδίων με περιεκτικότητα σε οξυγόνο μεγαλύτερη από ένα επίπεδο-στόχο, π.χ. 300 ppm, θερμαίνοντας το υδρίδιο μετάλλου υπό την παρουσία ενός άλλου μετάλλου με υψηλότερη συγγένεια για οξυγόνο, αφαιρώντας το άλλο μέταλλο και οποιαδήποτε υποπροϊόντα της αντίδρασης, έτσι ώστε να σχηματιστεί μία μεταλλική σκόνη με χαμηλότερη περιεκτικότητα σε οξυγόνο από το επίπεδο-στόχο και σχηματίζοντας ένα μεταλλουργικό προϊόν από την εν λόγω σκόνη Ta/Nb ανηγμένου οξυγόνου με περιεκτικότητα σε οξυγόνο μικρότερη από το επιθυμητό επίπεδο.
