High values of electrical conductivity are obtained at the detonation of condensed high explosives with the formula C a H b N c O d . 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. This work is devoted to the investigation of the detonation soot of high explosives with a significant carbon content in order to discover elongated structures supporting the contact conductivity hypothesis.
