Ignition of Powders of Aluminum Hydride and Metal Aluminum Hydrides behind Reflected Shock Waves

The characteristics of self-ignition of powders of aluminum hydride, sodium aluminum hydride, and titanium hydride in an atmosphere of air/oxygen are investigated experimentally. The self-ignition of these compounds is implemented behind reflected shock waves. A comparison with hydrogen self-ignition under conditions comparable in pressure and temperature is performed. For the first time, the closeness of delay times before the inclusion of the gaseous hydrogen and its heterogeneous carriers in the explosive transformation is demonstrated.
