    Abstract

    The burning of aluminum in NASA/ASTM flammability tests is examined for establishing a probable mechanism. Similarity between oxidation of pure solid and pure liquid aluminum surfaces suggest that a phase-boundary reaction occurs and that a Langmuir-Hinshelwood model is appropriate. Consistent evaluation of available data confirm that a phase-boundary reaction is highly probable. Vacuum evaporation and thermal energy considerations support this contention.
