The paper discusses the basic laws of the slow process of decomposition under the action of magnetic, contact electric fields and UV-irradiation in threadlike crystals of silver azide with additionally introduced impurities of iron and lead. The quantitative content of the introduced impurity was determined by means of atomic emission spectroscopy (atomic emission spectrometer with individually-coupled plasma iCAP 6500). Quantitative analysis of the decomposition products was performed with volumetric methods. The experimental results on the influence of impurities on the initiation of the decomposition reaction and the topography of the products of silver azide crystals decomposition were obtained. The authors propose a method of controlling the chemical ability of silver azide crystals with additional introduction of impurities of iron and lead having an effective influence on the nature of the reaction of solid-phase decomposition. The practical significance of the work is determined by the possibility of using experimental results for targeted control of stability and reactivity of silver azide, as well as explosive materials made on its basis.
