The TaN was also synthesized by shock compression (62). Shock compression recovery experiments with a porous sample of tantalum nitride with a hexagonal structure were performed in the impact velocity range up to 1.5 km s . The recovery rate of the Bl-type phase increased with increasing porosity. Almost 100% recovery was achieved for a powder of 70% porosity on impact by a 2-mm-thick tungsten plate with velocities above 1.4 km s . The shock-synthesized Bl-type tantalum nitride has good stoichiometry compared with combustion-synthesized ones. 

The combustion of tantalum in nitrogen was studied in detail by Borovinskaya et al.10 Experimental measurements of the propagation characteristics were reported and the various nitrides of tantalum were synthesized under appropriate conditions. The study also showed the use of the chemical furnace technique for the preparation of high-temperature metastable phases.
