摘要: 采用超临界气体抗溶剂（gas anti-solvent, GAS）技术制备了平均粒径为721.9 nm的亚微米级型六硝基六氮杂异伍兹烷（CL-20），应用傅立叶变换红外光谱（Fourier translation infrared spectrum, FT-IR），对亚微米级CL-20的晶型进行了鉴别，并进行了小隔板试验、撞击感度和爆发点测试。研究结果表明，细化后的亚微米级型CL-20冲击波感度的隔板厚度降低了58.6%，撞击感度的特性落高提高了84.1%，而爆发点保持不变。

Abstract: Submicron -CL-20 particles with the mean particle diameter of 721.9 nm were prepared by the gas antisolvent technology and were confirmed by the SEM results. Polymorphs of submicron -CL-20 were identified by FT-IR spectroscopy. Small-scale gap tests were performed for submicron -CL-20, and its impact sensitivity and ignition temperature were measured. The gap thickness decreases 58.6% and the characteristic droop is higher 84.1% than that of the raw material, while the ignition temperature with 5 s delay is the same as that of the raw material.
