Detonation Mechanism of PETN Explosives with Sodium Hydrocarbonate

The detonation of mixtures of highly dispersed PETN with sodium bicarbonate with a mass fraction of the latter up to 90% is investigated using radio interferometric method and electron-optical method NANOGATE-22 along with a method using a polyvinylidene fluoride pressure sensor. The experimental re...

Description
Summary:The detonation of mixtures of highly dispersed PETN with sodium bicarbonate with a mass fraction of the latter up to 90% is investigated using radio interferometric method and electron-optical method NANOGATE-22 along with a method using a polyvinylidene fluoride pressure sensor. The experimental results obtained indicate the possibility of the existence of various detonation regimes in mixtures. If the mass fraction of NaHCO 3 is  ≤ 85%, the detonation wave propagation is mainly due to shock compression. At a higher NaHCO 3 content (90%), the jets of explosion products predominantly serve as propagation agents.
