Incomplete reactions in nanothermite composites. [PDF]

open access: yesJ Appl Phys, 2017
Exothermic reactions between oxophilic metals and transition/post transition metal-oxides have been well documented owing to their fast reaction time scales (≈10 μs). This article examines the extent of the reaction in nano-aluminum based thermite systems through a forensic inspection of the products formed during reaction.
