Investigated the possibility of transition of deflagration to detonation salts of 5,5’- azotetrazole with the nitrogenous bases are: hydrazine, hydroxylamine, triaminoguanidine. It is shown that in the copper pipes in enclosed and semi-enclosed volume of the combustion of salts of 5,5’-azotetrazole of hydrazine and triaminoguanidine goes to the convective regime without transition to detonation. These salts do not possess the initiating ability for PETN. Only the salt of 5,5’-azotetrazole with hydroxylamine has the initiating ability, for which the minimum initiating charge for TNT is determined.
We have investigated the possibility of transition of burning to detonation and initiates the ability of the coprecipitated stoichiometric mixtures of salts of 5,5’- azotetrazole with triaminoguanidine and ammonia with oxidizers - chlorate and potassium perchlorate. It is shown that the copper tubes in these mixtures there is a transition to convective burning regime without transition to detonation, as 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 the oxidant potassium chlorate have an initiating ability for PETN.
