Abstract

The initiation of detonation in pressed finely dispersed explosives by a high-voltage electric discharge is studied. It is shown that this type of initiation can be greatly simplified by adding to the explosive metal (conductive) additives with a high specific heat capacity and thermal conductivity. It is established that the parameters of the initiating electric discharge depend on the fractal structure of the nanocrystalline explosive.
