Abstract

Electrical conductivity of explosion products behind the detonation front of emulsion explosives is measured. The composition of the emulsion matrix and the amount of the additive consisting of sensitizing glass microspheres are varied. The peak value of electrical conductivity for the examined compositions is 0.5–0.05 W–1 × cm–1.
