Abstract

The thermal decomposition of dihydroxylammonium 5,5′-bistetrazole-1,1′-diolate (TKX-50) with three different particle sizes were studied under adiabatic condition by using accelerating rate calorimeter (ARC). The adiabatic experiment revealed that TKX-50 had two decomposition stages. Based on the experimental results, the decomposition parameters including the thermal data and pressure data of three kinds of TKX-50 were used as the hazard assessment indicators. The results revealed that the decomposition of TKX-50 nanoparticles was the mildest among all of the samples in the first decomposition stage. In addition, the SADT of three kinds of TKX-50 with different sizes were predicted when stored in the wooden cylinder, and the results showed that TKX-50 milliparticles exhibited the best thermal stability.
