The influence of energy content and its outputs on the impact sensitivity of high-nitrogen energetic materials

Popis výsledku v původním jazyce

On 15 high nitrogen and three polynitrated polyazaarenes (including six azido-derivatives), the paper demonstrates the relations between their impact sensitivities (Edr) on the one hand and the volume heats (ρQmax) or a representative of detonation pressure (ρD2) of their explosion or their enthalpies of formation (ΔHform) on the other. The semi-logarithmic subrelations between the Edr and ρQmax values are limited by the mechanism of primary fission. While the mentioned relations between Edr and ρQmax values for azido derivatives predominantly show the expected course, in the case of the remaining high-nitrogen EMs, the opposite is the case, i.e., an increase in ρQmax values corresponds to a decrease in impact sensitivity. The same is valid for ρD2 values as an independent variable. Taking the energy content of the studied EM molecules, represented by ΔHform values, instead of the heat of explosion, yields unambiguous semilogarithmic relations, according to which the growth of the ΔHform values increases impact sensitivity. The results obtained indicate that it is necessary to distinguish between the influences of the performance and the energetic content of high-nitrogen energetic materials on their initiation reactivity.
