摘要: A tantalum powder having a value of hydrogen (H) content (ppm) of the tantalum powder divided by Brunauer-Emmett-Teller (BET) surface area (m2/g) of the tantalum powder (H/BET) is greater than 100 is provided. The tantalum powder can be used as an anode of a capacitor, such as a solid electrolytic capacitor, to obtain a capacitor having large capacitance and low current leakage. Methods of producing the tantalum powder, anode, and capacitors including the tantalum powder, also are provided.

摘要: A process and system for producing tantalum or other valve metal particles is provided comprising forming tantalum particles in a reduction process carried out in a reactor vessel, and using a siphon to transfer fine tantalum particles out of the reaction mixture to a recovery vessel. This particle transfer can occur while the reaction mixture is agitated. The tantalum particles can be automatically withdrawn when the reaction mixture has a depth level greater than the fluid level of the tantalum fine particle recovery vessel, and outflow automatically stops when the fluid levels of the reactor and particle recovery vessel equilibrate. Tantalum or other valve metal powders made by the processes, and capacitors made with valve metal powders are also provided.
