“…The choice of the object is determined by the fact that water-filled HEs (as opposed to plastic HEs) maintain to a significant extent the initial structures of particles and their size distribution when the samples under study. Furthermore, according to the studies (see, for example, [9]), the physical picture of the transformation of a shock wave into a detonation wave is identical in water-filled HEs and in solid heterogeneous HEs. Therefore, the assessment of the influence of internal defects, and in particular, of the annihilation of dislocations on the formation of local chemical reaction zones is simpler with the use of the water-filled systems.…”

The relation between the structural peculiarities of crystals of high explosives (HE) and their detonability is analyzed. It is shown that internal defects in HE crystals can significantly influence the critical diameter of detonation. Several technological ways for managing the defects of HE crystals are proposed and, thus, for the size of the critical detonation diameter (or the thickness of the detonating layer). The technique of HE thermal vacuum recrystallization is the best way to create compact devices of explosive logic and automation. This technique provides a significant decrease in the critical diameter of detonation with the maintenance of thermal stability and sensitivity to mechanical effects at the level of factory-manufactured HEs.
