Abstract
Metal additives are used in explosives and solid propellants in order to increase the energetic
output and effectiveness of the explosives or fuel. Aluminum has been the primary solid fuel
additive to solid fuel to improve the combustive properties of propellants. Several other metals
are being considered for explosive material applications, such as reactive materials, reactive
fragments, and metalized explosions. It is important to understand the burning characteristics of
these materials in order to optimize their use. This study focuses on comparing the spectroscopic
outputs of several energetic metals with that of aluminum. Spectroscopic analysis helps develop
optical diagnostics for systems involving combustions of advanced metals. A shock tube
experimental setup was used to ignite the powders, and resultant spectra were recorded. Metals
tested include aluminum, boron, magnesium, hafnium, zirconium, titanium, manganese, silicon,
strontium, and scandium. Finally, the resultant spectrum of each metal tested is explained, and
an analysis on the results was performed.
