Discussions on Influencing Factors of Mechanical Sensitivities of Energetic Materials Taking Dihydroxylammonium 5,5’-bistetrazole -1,1’-diolate as an Example

Abstract

Mechanical sensitivities of energetic materials are influenced by some factors, such as crystal type, particle size, additives, and so on. In literature, conclusions from different authors are often different, even opposite. In this paper, depending on experimental data by ourselves and amounts of data from literature, we discussed some factors influencing mechanical sensitivities of energetic materials. Results show that impact sensitivities of flaky energetic materials is usually higher than corresponding particle one, and friction sensitivity of energetic materials particles easier to roll is often lower. Although processing additives often lessen the mechanical sensitivities of energetic materials, in some case, mechanical sensitivities of energetic materials with binder increase obviously. The mechanism inducing erratic results of mechanical sensitivities of energetic materials in testing is discussed in this paper, too.
