LASER INITIATION OF THE MIXTURE OF TETRANITROPENTAERITRIT WITH METALS AND COMPOUNDS ENERGETIC NANOPARTICLES
Abstract
Thresholds of explosive degradation of PETN with different additives in the laser exposure were measured, with the additives being Al, Al-C, Ni, Co, «Kemerit ®», nanoparticles with different content Al/Al2O3. The expansion ve- locity of the explosion products of certain materials was measured. Thresholds of explosive decomposition were meas- ured with regard of the initial temperature and the melted extruded samples of Ni-C and Al. In prersence of 0.1 % Al as additive, the sensitivity is shown to decrease, as compared to samples containing no additives. This allows us to consid- er this part of mixtures a promising material for light detonators.
