Elongated conductive structures in detonation soot of high explosives.

High values of electrical conductivity are obtained at the detonation of condensed high explosives with the formula C H N O . Such values can be explained only in the framework of the contact conductivity hypothesis. In this case, the conductivity is provided by elongated highly-conductive structures which penetrate the whole space of the detonation wave.

Influence of the grain size of high explosives on the duration of a high conductivity zone at the detonation.

At the detonation of condensed explosives, on the profile of electric conductivity is observed the area of high values, which is usually associated with the chemical reaction zone. The new interpretation of experimental data on the electrical conductivity allows one to diagnose the influence of the grain size on the charge structure and the reaction zone in the whole range of densities investigated. The reliability of the proposed hypotheses are investigated by the methods of statistical analysis.
