The Diagnostics of the Chemical Reaction Zone at the Detonation of Condensed Explosives

Abstract

The highly-sensitive method is proposed for the real-time diagnostics of the chemical peak (von Neumann peak) at detonation of brisant high explosives. The absence of the direct link between the pressure and the course of chemical reactions was shown. For TNT, the influence of the structure of charge on the kinetics of chemical peak was demonstrated.

On the mechanism of carbon nanostructures formation at reaction of organic compounds at high pressure and temperature

“…It was established by the comparison of experimental data on the duration of the reaction zone and the region of high conductivity that the maximum value of conductivity σ max is reached inside the reaction zone. 19,22,23 Chemoionization is thought to be the most probable cause of conductivity in the chemical peak region. The concentration of charge carriers n due to chemoionization is by definition connected with the number of reacted molecules.…”
