Abstract
Metal hydride has been used as a potential energetic material due to its high hydrogen storage density, high reactivity, high mass calorific value and large gas production. But it was still a great challenge towards optimizing and enhancing the energy-releasing properties of metal hydride. In this work, a novel molecular perovskite energetic material (H2dabco)[NH4(ClO4)3] (DAP-4) was introduced as a high energy oxidant to fabricate metal hydride (MH2, M=Mg, Ti, and Zr) based energetic composites. The thermal decomposition, ignition and combustion characteristics of MH2-based energetic composites were studied. The results showed that molecular perovskite energetic material DAP-4 was beneficial as oxidant in MH2-based high-energy solid composites, which were originated from its high energy properties and strong oxidation capacity. The ignition and combustion reaction mechanisms of MH2 with DAP-4 as oxidant were provided. This work offered an effective way to realize energy-releasing performance of MH2 by molecular perovskite energetic materials introduced for their potential application.
