Abstract: Researchers are attempting to prepare smaller (nano-scale) metal particles, and nano-scale thermitic (metal–metal-oxide) composites. When added to energetic compositions, these nano-materials could burn during or close behind the shock front produced by an explosive material. Therefore, investigation of their combustion kinetics is important, especially when the investigation technique requires only very small quantities of material that is initially prepared. This study uses time-resolved emission spectroscopyto measure reaction kinetics and mechanisms of micrograms of material initiated by a laser pulse. Results from nano-scale aluminum and the thermite-type compositions of Al+Fe2O3, Al+MoO3, and Al+B2O3 are presented here.
