Abstract:
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 during dispersion of the pressed pellet material in a rarefaction wave was investigated. From the results of pyrometric measurements, the maximum brightness temperature of chemical reaction products was ≈3 500 K.
Keywords:
thermite compositions, shock-wave initiation, chemical reaction, detonation.
