The Al/α-AlH3 was prepared in ether solution with LiAlH4 and AlCl3 with some addition. The crystallization and the morphology of the prepared samples were studied by X-ray diffraction (XRD) and Scanning electron microscopy (SEM). The organic elemental analyzer can be used to determine the content of H element. Furthermore, the effects of Al on the thermal stability and security of α-AlH3 were also studied. The thermal stability has been studied by TG curves. The impact sensitivity test, friction sensitivity test and electrostatic spark sensitivity test have been tested. The results shown that the existence of the Al has no impact on the friction sensitivity, impact sensitivity of pure α-AlH3. However, the existence of Al increases the decomposition rate of α-AlH3.
