Study on the Preparation and Composition of Ultrafine CL-18/HNS

Abstract

Using solvent-nonsolvent method, study on the preparation and composition of ultrafine CL-18/HNS. Scanning electron microscopy (SEM) was used to characterize the particle size and morphology. The FTIR spectra (IR), differential scanning calorimetry (DSC) and X-ray diffraction (XRD) were utilized to determine whether the cocrystal explosive was prepared. Furthermore, the impact sensitivity and short pulse slapper sensitivity of cocrystal explosive was tested. Results show that the prepared samples are the mix of CL-18 and HNS but rather changed cocrystal appearance of ultrafine CL-18/HNS. The average particle size of cocrystal explosives are 0.98μ. The peak temperatures of exothermic decomposition are 205.36 °C, The impact probability of CL-18/HNS cocrystal explosives is 56 percent, and minimum initiation energy is 0.12J.
