It is experimentally shown that for metal salts of azoles there is no universal factor determining the processes of deflagration under thermal and laser initiation. For the series of azoles having a common initial stage of thermal degradation, the step of deflagration-to-detonation transition (DDT) for the same metal cation depends on ΔHf0 value of the salt. At the same time within the range of silver salts of isomeric N-nitroaminotetrazoles ΔHf0 values of the compounds, their structure, reactivity of the products of the initial decomposition and the composition of gaseous products of burning all influence their initiating ability under thermal initiation. But the ionization potential of complex perchlorates of d-metals with 3(5)-hydrazino-4-amino-1,2,4-triazoles as ligands determines the intensity of initial steps of decomposition under laser initiation which, in its turn controls the threshold of ignition. Hence the knowledge of the nature of initial decomposition stages of azole salts, taking into account the mechanism of energetic effects, is necessary for prediction of their behavior under initiation.

This article focuses on an investigation of the optical initiation of the light-sensitive energetic complex perchlorates 3(5)-hydrazino-4-amino- 1,2,4-triazole copper(II) perchlorate and 1-H-5-hydrazinotetrazole mercury(II) perchlorate. It is shown that light emission initiates an explosion in energy-rich formulations (compositions) based on these complexes, EC-1 and EC-2 respectively. It was found that the pyrotechnic formulation EC-2 containing the mercury complex may be used to initiate detonation in highly energetic materials.

Development of condensed energetic systems, especially photosensitive primary explosives for the systems of laser initiation is one of the foremost fields of application of energetic materials. There have been synthesized and investigated a coordination complex of mercury(II) chlorate(VII) with 5-hydrazinotetrazole as ligand (compound (I)) as a potential photosensitive primary explosive. This complex consisting of particles of 1.1 0.8 m size demonstrated the highest sensitivity to laser irradiation combined with an extremely low initiation threshold. On the basis of compound (I) a photosensitive formulation EC-2 containing ∼ 90% of the complex mercury(II) chlorate(VII) and ∼ 10% of an optically transparent polymer as an inert matrix has been proposed. Formulation EC-2 has extremely high sensitivity to Q-switch IR-laser irradiation. Formulation EC-2 with added ultra disperse diamonds (UDD) has shown lower initiation thresholds in comparison with neat EC-2 or EC-2 with added submicron black carbon, fullerens or nanotubes instead of UDD.

Methods for the synthesis of novel energetic complex perchlorates of d-metals have been developed. According to derivatographic analysis data, the complexes are thermally stable compounds. One of the promising ways of regulating ballistic characteristics of highly filled energetic formulations is the introduction of burn modifiers. Complex compounds of d-metals are known to be effective modifiers of the process of burning. Ballistic tests were made in a constant pressure bomb and demonstrated that the prepared compounds are promising modifiers of the burn rate and can be used in the developed formulations of rocket propellants.
