| Abstract Scope |
This study examines interaction of metal oxide particles, generated during the combustion of metal fuels, with chemical warfare agent (CWA) simulants to enhance decomposition. Diisopropyl methyl phosphonate (DIMP) serves as a surrogate for CWAs in experiments. The focus is on aluminum oxide powders mixed with soil components like CaCO3, SiO2, and Fe2O3, synthesized in a Constant Volume Explosion setup. The collected smoke samples, containing mixed oxide phases and unreacted metal fuel, mimic real combustion environments. The properties of the combustion products are quantified and correlated with test conditions and energetic performance. These metal oxides are then tested for their ability to promote DIMP decomposition by heating the mixture to 350 °C, beyond DIMP’s boiling point of 200 °C, and calculating mass loss. Post-reaction residues are analyzed using FTIR-ATR to characterize surface interactions. Findings show that combustion-derived oxides significantly enhance CWA surrogate breakdown, suggesting a synergistic effect between combustion heat and oxide properties. |
