VERFAHREN ZUR HERSTELLUNG VON NIOB- UND TANTALPULVER
摘要:
The invention relates to a method for the production of valve metal powders, particularly niobium and tantalum powder, by reduction of corresponding valve metal oxide powders by means of vaporous reducing metals and/or the hydrides thereof, preferably in the presence of an inert carrier gas, wherein the reduction is carried out at a reducing metal/metal hydride vapor partial pressure of the of 5-110 hPa and at a total pressure of less than 1000 hPa, and to a tantalum powder thus produced, with high-stability powder agglomerate particles.
