Abstract: High Resolution Image Download MS PowerPoint Slide In order to achieve new energetic materials with high energy, low sensitivity, and moisture-proof properties, dihydroxylammonium 5,5′-bistetrazole-1,1′-diolate (TKX-50)/ammonium perchlorate (AP) cocrystal (molar ratio 1:1) was successfully prepared through a spray-assisted solvent–nonsolvent method. SEM shows that the morphology of the cocrystal is different from those of the two raw materials. XRD and FT-IR spectra indicate the formation of the cocrystal. The apparent activation energy of the cocrystal is lower than that of raw TKX-50. The characteristic drop height ( H 50 ) is higher than that of TKX-50, while the friction sensitivity ( P ) of the cocrystal is lower. In addition, the moisture-proof property of the cocrystal is improved, showing good application potential.
