Description

Tantalum nitride (Ta2N) nanocrystallites have been firstly direct synthesized by dc arc discharge and characterized by XRD, TEM, FTIR techniques. The average size of Ta2N nanocrystallites is about 5-10 nm. The influence of NH3 concentration of the reaction gas on the as-synthesized Ta2N is studied and it is found that the optimal NH3 concentration of the reaction gas to synthesize single-phase Ta2N was in the range of 10-20%. The growth mechanism of Ta2N was discussed. This synthetic method may be suitable for a direct preparation for mass production of Ta2N nanocrystallites
