| Abstract: | Post treatments including granulation and deoxidization using magnesium as the reducing agent were carried out on the tantalum nitride nanopowders which synthesized by homogeneous reduction in liquid ammonia. The physical and chemical properties of the powders such as phase composition, morphology, oxygen content, and specific surface area were analyzed by XRD, FESEM, TEM, O-N-H analyzer and automatic gas adsorption measurement by the BET method. The results demonstrated that the physical and chemical properties of the tantalum nitride nanopowders had improved significantly and suitable for manufacturing tantalum capacitor with ultrahigh specific capacitance. |
