Shock-Wave Initiation of a Thermite Mixture of Al + CuO

  • Published:
Combustion, Explosion, and Shock Waves Aims and scope

Abstract

The shock-wave initiation of chemical reaction in pressed pellets of a stoichiometric mixture of Al and CuO powders in a steel tube was studied. The dynamics of the chemical transformations in the heterogeneous flow of reaction products of the mixture with dispersion of the pressed pellet material in the unloading wave was investigated. From the results of pyrometric measurements, the maximum brightness temperature of chemical reaction products was \(\approx\)3500 K.
