“…X-ray powder diffraction data were analyzed to investigate the composition and microstructure of raw HMX, FOX-7, and samples (Figure a). Strong diffraction peaks for FOX-7 are located around 14.9°, 15.4°, 19.9°, 20.5°, 26.7°, 27.9°, 29.9°, 31.1°, 33.8°, and 38.3°, which are consistent with the characteristic diffraction peaks reported in the literature . The strong diffraction peaks of HMX are at 14.6°, 15.9°, 20.4°, 22.9°, 26.1°, 27.1°, 27.9°, 29.6°, 31.8°, and 50.6°.…”
