Abstract

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.
