The nature of exothermic reactions in highly dispersed initiating explosives

Highly dispersed initiating explosives and igniting compositions based on them in the form of an aqueous suspension and paste have been obtained, which can significantly improve the safety of the technological process of equipping pyrotechnic initiation devices. The properties of the obtained explosives are analyzed, and the scope of their application in the form of film pyroelements is proposed. A visual - thermal analysis of the exothermic transformation in film pyroelements under normal conditions has been performed. It has been shown that high-temperature exothermic reactions do not occur in the form of a detonation wave, but in the form of stationary layered combustion at the rate of 20 to 200 mm/s under normal conditions, with intense release of dispersed products and flames.
