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.
