Synthesis of Tantalum Nitride

Undiluted Ta samples without preheating Sample density 

For all three reaction systems, the propagation velocity of the self-sustaining combustion wave increased with nitrogen pressure, but decreased with sample compaction density. Heating the green samples prior to ignition also led to 

For the V/N2 reaction system, a significant enhancement of the conversion percentage was achieved for the VN-diluted vanadium compact, due mainly to melting of the undiluted samples. Preheating also improved the nitridation of the VN-diluted sample, thus leading to a nitride yield over 90% obtained from a 30-wt% VN-diluted sample under preheating at 100-200 °C. For the Nb/Nj
