Abstract
The present paper gives new experimental results that allow slow decomposition of metal azides of different types (including radiolysis, photolysis, electrolysis, and thermolysis) to be analyzed in the context of the common reaction pathway. Filamentary crystals of silver and lead azides are investigated. It is demonstrated experimentally that the reaction goes on the vacancy cluster formed by an edge dislocation in the near-surface region of the crystal. The reaction produces nonequilibrium electrons and holes considered as reactants. In the bulk of the crystal, the reaction in the anionic sublattice forms an intermediate product, hypothetically, N6. Methods of controlling the defect crystal structure of metal azides are suggested. They allow the reactivity of metal azides to be preset.
