The high-pressure behavior of bis(nitroxymethylisoxazolyl) furoxan (DNDIF) was studied at ambient temperature and pressures approaching 30 GPa by Raman spectroscopy and powder X-ray diffraction. There was no evidence of a phase change observed over this pressure range, indicating that the ambient structure of DNDIF remains stable up to conditions similar to the detonation pressure of the material. Such findings suggest that this melt-castable explosive may be used in the replacement of 2,4,6-trinitrotoluene (TNT) in energetic formulations without the concern of uncontrolled polymorphism that might otherwise affect the performance and safety of the munition. Additionally, empirical understanding of the effect of different structural motifs in the crystal packing builds on understanding of what macroscale features are desirable for future materials and gets us closer to the design of future novel energetics.

可熔浇注高能材料的高压表征：双（硝基甲基异恶唑基）呋喃 (DNDIF)

通过拉曼光谱和粉末 X 射线衍射在环境温度和接近 30 GPa 的压力下研究了双（硝基甲基异恶唑基）呋喃 (DNDIF) 的高压行为。在此压力范围内没有观察到相变的证据，表明 DNDIF 的环境结构在与材料爆震压力相似的条件下保持稳定。这些发现表明，这种可熔铸炸药可用于替代高能配方中的 2,4,6-三硝基甲苯 (TNT)，而无需担心不受控制的多晶现象，否则可能会影响弹药的性能和安全性。此外，
