Patent ID: 8205608

Claim:
A hydrogen suppressing, flameless, heat generating chemical composition comprising a reaction mixture having at least the following reactants: magnesium with small trace amounts of alloying metals in the range of 0.001% to 0.1% selected from the group consisting of: iron, cobalt, nickel, zinc and aluminum water; particulate carbon; a hydrogen overvoltage suppressor; a flowing agent; a reaction activator selected from the group consisting of: an inorganic salt, a thermally and electrically conducting, high surface area synthetic graphite, a conducting carbon, a conducting graphite and combinations thereof; and, a hydrogen suppressor selected from the group consisting of: γ-MnO 2 , oxides of ruthenium, PtO, IrO 7 , RhO 7 , Fe 2 O 3 , Co 3 O 4 , NiO, Ag 2 O, Au 7 O 3 , TiO 2 , ZrO 2 , HfO 2 , Ta 2 O 5 , PbO 2 , and combinations thereof, and each of said reactants being present in a proportional amount to generate sufficient heat to heat water, medical supplies and/or consumable rations, wherein said chemical composition is placed in a reaction mixture bag made to be hydrophilic by dipping said reaction mixture bag in an aqueous solution containing a surfactant or by applying a dab of said aqueous solution containing said surfactant on a side of said reaction mixture bag.
