Mixtures of nanoaluminum (nAl) and dilute hydrogen peroxide (HP) were studied to determine their potential to detonate when subjected to explosive shock. Results of explosively driven rate stick experiments revealed steady shock propagation for stoichiometric mixtures of nAl and 10wt% HP. The critical diameter of this composition is estimated to be between 27.7 and 34.5mm. Detonation velocities between 3.034 and 3.187mm/s were obtained, varying with charge diameter and density. This represents the first measured shock-driven, self-sustained reaction in nAl and dilute HP mixtures.
