MgH, MgNiH, and MgCuH were prepared, and their structure and hydrogen storage properties were determined through X-ray photoelectron spectroscopy and thermal analyzer. The effects of MgH, MgNiH, and MgCuH on the thermal decomposition, burning rate, and explosive heat of ammonium perchlorate-based composite solid propellant were subsequently studied. Results indicated that MgH, MgNiH, and MgCuH can decrease the thermal decomposition peak temperature and increase the total released heat of decomposition. These compounds can improve the effect of thermal decomposition of the propellant. The burning rates of the propellant increased using Mg-based hydrogen storage materials as promoter. The burning rates of the propellant also increased using MgH instead of Al in the propellant, but its explosive heat was not enlarged. Nonetheless, the combustion heat of MgH was higher than that of Al. A possible mechanism was thus proposed.
制备了 MgH、MgNiH 和 MgCuH，并通过 X 射线光电子能谱和热分析仪确定了它们的结构和储氢性能。随后研究了 MgH、MgNiH 和 MgCuH 对高氯酸铵基复合固体推进剂热分解、燃速和爆炸热的影响。结果表明，MgH、MgNiH 和 MgCuH 可以降低热分解峰温度并增加分解的总放热量。这些化合物可以改善推进剂的热分解效果。作为促进剂，使用基于镁的储氢材料可以提高推进剂的燃速。用 MgH 代替推进剂中的 Al 也可以提高推进剂的燃速，但不会增加其爆炸热。然而，MgH 的燃烧热高于 Al。因此，提出了一种可能的机制。
