Flare Chemistry Oxidizer

• Responsible for K peaks• Produces oxygen to burn

flare. Combustible binder added to

slow burn rate; produces brighter intensity

Composition• Generally 55% Mg, 38%

NaNO3, and 6% binder• Ferric Oxide functions as

ignition and incendiary Color intensifiers

• Lithium carbonate added to give red color.
