Thermal behavior and combustion mechanism of high-nitrogen energetic materials DHT and BTATz

► High-nitrogen energetic materials DHT and BTATz. ► First stage of DHT decomposition is redox process. ► Preliminary reactions of tetrazole isomerization during BTATz decomposition is the reason of the large observable activation energy. ► Unique information on decomposition kinetics of energetic materials at high temperatures. ► Explanation of the unusual DHT combustion behavior.
