  • Melt cast insensitive eutectic explosive
    Patent number: 8663406
    Abstract: A insensitive explosive comprises: 34.9 wt % diethylenetriamine trinitrate (DETN), 33.4 wt % ethylenediamine dinitrate (EDD), 25.4 wt % methyl-guanidine (MeNQ), and 6.3 wt % guanidine (NQ). This quaternary eutectic is used in combination with a sensitive explosive. A low melting temperature facilitates melt casting to fill 155 mm artillery shells.
