ON THE MECHANISM OF DETONATION COMBUSTION OF NANOSTRUCTURED SILICON WITH A SOLID-PHASE OXIDANT

The physical mechanism of detonation combustion of nanostructured silicon with a solid-phase oxidant at a velocity of the combustion front of 1000–3000 m/s has been proposed. Thermodynamic characteristics of combustion of model solid-phase mixtures "silicon–ammonium perchlorate" with different equivalent ratios of their components have been calculated at different pressures. It has been established that a characteristic feature of detonation combustion of nanostructured silicon with a solid-phase oxidant is the stationary velocity of motion of the detonation front with a signifi cant defect (10–15%) with respect to the Chapman–Jouguet detonation velocity. The detonation (supersonic) and subsonic regimes of combustion of nanostructured silicon with a solid-phase oxidant have been determined.
