TL;DR: In this paper, the authors investigated the effects of the heating rate and sample amount on the safety performance of dihydroxylammonium 5,5-bistetrazole-1,1ʲ-diolate (TKX-50) decomposition.
Abstract: The pressure characteristics and safety performance of dihydroxylammonium 5,5ʹ-bistetrazole-1,1ʹ-diolate (TKX-50) decomposition were studied in confined space by using the accelerating rate calorimeter (ARC). The effects of the heating rate and the sample amount on the safety performance were investigated. The experiment results revealed that high heating rate was harmful to the safety performance of TKX-50. The decomposition mechanism did not change when using different amounts of sample in the range between 47.5 and 72.5 mg. After ignition, TKX-50 exhibited better safe performance than RDX and HMX.
