Abstract

The presence of aluminum monoxide (AlO) is often used as an indicator of aluminum combustion; however, a recent study has indicated that explosive fireballs are optically thick. Therefore, external measurements are biased towards conditions near the fireball surface. A combination of optical techniques and analysis of recovered residue is used to challenge typical interpretations of optical measurements of aluminized explosive fireballs. Tests in four environments show that even when AlO emission intensity is quite small, it is possible to have significant aluminum particle oxidation. In addition, substantial AlO emission is measured in the absence of unburned aluminum. As a result, the interpretation of AlO emission is not straightforward with respect to correctly determining the amount of aluminum combusted.
