Ignition of Initiators by an Electrical Spark

Abstract

At present there are two contradictory opinions on the initiation of inorganic azides by an electrical spark. On the one hand, authors of a number of works [1-3] put thermal effects connected with the development of the discharge channel in the first position and show that initiation of the reaction occurs only when in the spark channel a certain minimal energy is released. On the other hand, in works [4, b] the main role is taken by the rapid reactions of the excited particles, and the nonthermal mechanism of excitation of the detonation process is assumed possible. The experimental data available at the present time make it possible to speak about the existence of a minimal volume of the center of warm-up, with the achievement if the critical value of the density of energy in which further independent development of the process is possible.
