Study of the Thermal Decomposition and Combustion of Guanidinium 5,5’-Azotetrazole Salt

The thermal decomposition and combustion of guanidinium 5,5’-azotetrazole salt (Gu2AzT) have been investigated. Temperature profiles in the Gu2AzT combustion wave were measured using thin tungsten-rhenium micro thermocouples. It was shown that combustion of the salt obeys the condensedphase mechanism. The high burning rate of Gu2AzT is connected with the high decomposition rate in the melt. The kinetic parameters of the controlling chemical reaction have been estimated, and a detailed combustion mechanism for Gu2AzT has been proposed.
