Spray flash evaporation, a promising path to fundamental research and industrial processes: elaboration of a micronized mixed HMX/LLM-105 energetic material

HMX and LLM-105 are well known energetic materials with, respectively, high performance and low sensitivity. In this work, we present a Spray Flash Evaporation (SFE) based process to form a HMX_SFE material as well as a novel energetic material containing HMX and LLM-105 ("HMX/LLM-105_SFE"), with a peculiar crystalline composition. These materials contain, respectively, notable amounts of α-HMX and an intimate mix between HMX and LLM-105 with distinct crystalline structures retained. Their sensitivity was evaluated, allowing exploration of the complexity of mixed materials' mechanical sensitivity and the potentialities of the SFE process for both industrial applications and fundamental research purposes.
