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.
