Research efforts for realizing safer and higher performance energetic materials are continuing unabated all over the globe. While the thermites - pyrotechnic compositions of an oxide and a metal - have been finely tailored thanks to progress in other sectors, organic high explosives are still stagnating. The most symptomatic example is the longstanding challenge of the nanocrystallization of 1,3,5-trinitroperhydro-1,3,5-triazine (RDX). Recent advances in crystallization processes and milling technology mark the beginning of a new area which will hopefully lead the pyroelectric industry to finally embrace nanotechnology. This work reviews the previous and current techniques used to crystallize RDX at a submicrometer scale or smaller. Several key points are highlighted then discussed, such as the smallest particle size and its morphology, and the scale-up capacity and the versatility of the process.
全球范围内，为实现更安全、高性能含能材料的研究工作仍在持续且热度不减。尽管由于其他领域的进展，铝热剂（一种氧化物与金属的烟火组合物）已得到精细调整，但有机高爆炸药仍停滞不前。最典型的例子是1,3,5 - 三硝基全氢 - 1,3,5 - 三嗪（RDX）纳米结晶这一长期存在的挑战。结晶过程和研磨技术的最新进展标志着一个新领域的开端，有望引领热电行业最终接纳纳米技术。本文综述了此前及当前用于将RDX结晶至亚微米级或更小尺寸的技术。随后突出并讨论了几个关键点，如最小粒径及其形态，以及该过程的放大能力和通用性。
