Onium salts of 5,5‘-azotetrazole are high-energy density materials which might find application in gas generators, initiators, or as additives for low-smoke solid rocket propellants. It is obvious, that a comprehensive understanding of combustion behavior and mechanism of an energetic material is essential to predict its performance in practical application. In the present paper, salts of 5,5‘-azotetrazole with ammonia, hydrazine, hydroxylamine, ethylenediamine, guanidine, aminoguanidine, diaminoguanidine and triaminoguanidine have been investigated with respect to combustion behaviour and mechanism. Thermocouples-aided studies of temperature distribution in the combustion wave of the studied salts were performed with the help of thin tungsten-rhenium microthermocouples. Analysis of temperature profiles, thermal decomposition and combustion behaviors of the studied salts allowed the mechanism of burning of the salts to be proposed.
