Promising energetic materials composed of nanosilicon and solid oxidizers

摘要

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