Abstract
A pyrotechnic composition produced by mixing and permitting to cure a mixture of aluminum, calcium sulfate, magnesium sulfate, and water. Increased heat output and density and improved ignitability result, while exotherm during curing can substantially be eliminated.
Claims8
A pyrotechnic product produced by mixing fully divided aluminum metal, calcium sulfate, magnesium sulfate, and water, the weight ratio of aluminum to calcium sulfate hemihydrate being between about 15%/85% to about 60%/40%, the magnesium sulfate being in the molar ratio relative to calcium sulfate of about 1/2, and about 6 moles of water per mole of magnesium sulfate, all of the foregoing ratios being based upon anhydrous sulfates, the calcium sulfate being calculated as hemihydrate.
A pyrotechnic product produced by mixing fully divided aluminum metal, calcium sulfate, and water, the weight ratio of aluminum to calcium sulfate hemihydrate being between about 15%/85% to about 60%/40%, and water sufficient for mechanical mixing, the calcium sulfate being calculated as hemihydrate.
