Patent ID: 7807000

Claim:
A thermobaric explosive composition, consisting of: coated fuel particles comprising metallic cores and an aluminum coating, wherein the metallic cores comprise a metal other than aluminum, the metal has a higher reactivity with carbon dioxide and water than aluminum, and wherein the aluminum coating includes a thickness selected to provide an amount of aluminum that undergoes sufficient aerobic combustion to expose the metallic cores in a first overpressure stage following detonation of the thermobaric explosive composition; a nitramine for dispersing the coated fuel particles over a blast area where the fuel particles aerobically combust during the first overpressure stage; and a binder, wherein the aluminum coating comprises aluminum and an aluminum oxide outer protective layer on the aluminum, and wherein the aluminum is a non-alloy aluminum material where the aluminum coating surrounds the metallic cores, and wherein said aluminum oxide outer protective layer comprises less than one (1) volume percent of each particle of said coated fuel particles, and wherein the coated fuel particles include an average particle diameter of about 0.1 micron to about 50 microns.
