Abstract

Spherical DADNE/AP (1,1-diamino-2,2-dinitroethylen/ammonium perchlorate) energetic composites were produced by drown- ing-out/agglomeration (D/A). The agglomeration of DADNE with AP particles was found to be affected by the amount of the bridging liquid, stirring velocity and residence time. The composites appeared to grow dramatically with the amount of bridging liquid which triggers agglomeration. As the stirring velocity and the residence time increased, the size of composites increased and then tended to decrease. Thermal gravimetric analysis showed that the addition of DADNE activates the low temperature decomposition (LTD) of AP. For the neat AP, the only about 30 wt% of AP was found to decompose at the LTD. On the other hand, it was found that 70 wt% of AP decomposed when DADNE was added by physical mixing and 90 wt% of AP decomposed when the DADNE/AP composites were prepared by the D/A method.
