Abstrakt:
A novel energetic co-crystal based on 1,4-dinitro-1,4-diazabutane (EDNA) and 1,5-diaminotetrazole (DAT) in a 1:2 molar ratio was synthesized. The formation of the cocrystal was monitored by Scanning electron microscope (SEM), powder X-ray diffraction (PXRD) and Raman spectroscopy. Sensitivity to impact was measured and 50% probability of initiation was 9.73 J for the cocrystal and 15.4 J for the EDNA. In addition, the detonation characteristics were predicted by EXPLO5 Code. The detonation velocity (D) and the detonation pressure (P) of the cocrystal are 8254.5 m s-1 and 26.7 GPa respectively. The obtained cocrystal possesses a promising future for expanding the reuse of EDNA in antitank ammunition after overcome the acidity problem with the explosive in addition, the higher nitrogen content and acceptable sensitivity to external stimuli.
