Abstract

By the example of 14 compounds representing the main classes of explosives containing H, C, N, and O, it has been shown that the impact sensitivity correlates with the critical temperature Tcr of spontaneous ignition, which, in turn, is determined by the kinetic parameters and heat of the decomposition reaction. At the same time, the reaction rate is the dominant factor, and against its background the effect produced on the sensitivity by the thermophysical properties of the compounds and by the specific coefficient of friction becomes barely noticeable.
