process for the manufacture of niobium and tantalum powder |
abstract |
PROCESS FOR THE MANUFACTURE OF NIOBIO DUST AND DENTAL POWDER. Process for the manufacture of valve metal powders, especially niobium and tantalum powders by reducing the corresponding valve metal oxide powders by means of steam-reducing metals and / or their hydrides, preferably in the presence of an inert carrier gas, the reduction being effected with a partial vapor pressure of the metal / reducing metal hydride of 5 to 110 hPa and a total pressure of less than 1000 hPa and the tantalum powder thus obtained with a high stability of particle board powder. |
