发明名称 Conversion of Ta2O5 to Ta metal
摘要 Processes for producing valve metal are described, in which valve metal oxide is converted to valve metal using a vapor-phase transport agent to form a gaseous valve metal species in the presence of a solid getter material. Also described is the valve metal so produced, and anodes prepared from the valve metal, as well as electrolytic capacitors using the anodes.
