Abstract

A method for production of mechanically activated energetic compositions consisting of nanosil� icon and solid inorganic oxidizers is developed. For the compositions prepared, both highspeed burning and detonation are observed. The propagation of the reaction is accompanied by a high energy release, compara� ble to the heat of explosion of aluminized high explosives. The compositions are highly sensitive to thermal stimuli and capable of rapid deflagrationtodetonation transition. The results obtained in the work suggest that nanosiliconbased formulations as promising ener getic materials for a wide range of applications, from initiating compositions in blasting caps to compositions for small charges in microsystem devices.
