INITIATING ABILITY OF SALTS OF 5,5'-AZOTETRAZOLE AND THEIR MIXTURES WITH OXIDANTS
The AzT salts are interesting as perspective oxygen-free, high-enthalpy, and low-sensitivity components of energetic compositions. The possibility of deflagration-to-detonation transition in salts of 5,5'-azotetrazole with the nitrogenous bases (hydrazine, hydroxylamine, and triaminoguanidine) is investigated. It is shown that in the copper tubes in enclosed and semienclosed volume, combustion of salts of 5,5'-azotetrazole of hydrazine and triaminoguanidine transitions to the convective burning regime without transition to detonation. These salts do not exhibit the initiating ability for PETN. Only the salt of 5,5'-azotetrazole with hydroxylamine exhibit such an initiating ability, for which the minimum initiating charge for TNT is determined. The possibility of deflagration-to-detonation transition and initiating ability of the coprecipitated stoichiometric mixtures of salts of 5,5'-azotetrazole with triaminoguanidine and ammonia with oxidizers (chlorate and potassium perchlorate) have been investigated. It is shown that in the copper tubes, in these mixtures, there is a transition to convective burning regime without transition to detonation as in previously investigated individual salts. In contrast to the individual salts of 5,5'-azotetrazole, mixtures of salts of 5,5'-azotetrazole with triaminoguanidine and ammonia with potassium chlorate exhibit an initiating ability for PETN.
