Nitriding tantalum powder

摘要

The leakage stability of sintered anode tantalum capacitors is enhanced, consistent with use of high capacitance yielding, micron size powder particles by a process of forming the micron size tantalum powder particles, deoxidation and nitriding after the deoxidation to thereby stabilize oxygen content at the particles' surfaces so that capacitance fall and leakage rise in anodes made from the particles are limited.
