KINETIC CHARACTERISTICS OF EXPANSION OF LEAD AND SILVERAZIDES WHISKERS UNDER PHOTOAND ELECTRIC-FIELDEFFECTS

The paper addresses the kinetics of the expansionn of lead and silver azides whiskers under photoand electricfield effects. The significant influence of charge heterogeneities (strong fielddomains) on the formation of solid (metal) and gas (nitrogen) degradation products is shown, appearing in the bulk of the azide in the fields of elastic stresses and dislocations, and in the contact area of the external electric field. The processes in the domain determine the kinetic features of electric-and photochemical decomposition of heavy metal azides and their high explosive sensitivity.
