Conclusions

  1. 1.

    The refractory tantalum carbides can be successfully prepared by the SHS method when the following conditions are fulfilled: a) Pure starting materials (Ta and C powders) are used and the metal powder is of small particle size; b) the process is performed in a large (adiabatic) reactor with a maximum reaction mass charge.

     
  2. 2.

    The phase composition of the resultant products is strongly affected by the density of the starting charge and the synthesis temperature.
