Decomposition of Lead Azide, Pentaerythrite Tetranitrate, and a Laminate System Composed of These Substances under Vibrational Loading

摘要

Decomposition of lead azide (LA), pentaerythrite tetranitrate (PETN), and a laminate system composed of these substances under vibrational loading is considered. Sensitivity of these substances to impact and vibrations is determined. Sensitivity of the LA + PETN laminate system to vibrational loading, which is characterized by the degree of decomposition, is substantially higher than that of PETN, but lower than that of LA. Specific features of the mechanism of decomposition of these substances at moderate values of vibration parameters and temperatures of specimen heating are discussed.
