Title (EN) CONVERSION OF Ta2O5 TO Ta METAL
(FR) CONVERSION DE TA2O5 EN MÉTAL Ta
Abstract: front page image
(EN)Processes for producing valve metal are described, in which valve metal oxide (Ta205) is converted to valve metal (Ta) using a vapor-phase transport agent (I2) to form a gaseous valve metal species (TaI5) in the presence of a solid getter material (Mg). Also described is the valve metal so produced, and anodes prepared from the valve metal, as well as electrolytic capacitors using the anodes.
(FR)L'invention concerne des procédés permettant de produire un métal à effet de valve, consistant à convertir un oxyde métallique (Ta205) à effet de valve en métal (Ta) à effet valve au moyen d'un agent transporteur (I2) en phase vapeur, de manière à former une espèce métallique (TaI5) à effet de valve sous forme gazeuse, en présence d'un matériau sorbeur (Mg) solide. L'invention concerne également le métal à effet de valve résultant et des anodes préparées à partir de ce métal à effet de valve, ainsi que des condensateurs électrolytiques comprenant ces anodes.
