A mixture and method of creating the mixture includes mixing hexachloroethane, stannous oxide, and aluminum together. The mixture may be loaded into at least one canister. The mixture may be combusted to create a smoke screen. The loading of the mixture into the at least one canister may include pressurized loading at loading pressures in the range of approximately 2300 psi to 3600 psi. The hexachloroethane may include approximately 30-40 parts by weight of the mixture and have a particle size of approximately less than 850 m. The stannous oxide may include approximately 55-65 parts by weight of the mixture and have a particle size of approximately less than 150 m. The aluminum may include approximately 5-10 parts by weight of the mixture and have a particle size of approximately less than 45 m. The mixture is devoid of zinc chloride.

Hydrolysis of water-reactive nanoporous nonprecious metals to produce hydrogen fuel on-demand for non-stationary applications is a promising method to overcome infrastructural limitations associated with current hydrogen storage and delivery systems. However, the pyrophoricity of highly reactive nanoporous nonprecious metals presents a safety and stability issue. Herein we demonstrate a method to stabilize pyrophoric nanoporous nonprecious metals by using a composite pellet structure consisting of a nanoporous nonprecious metal and a highly hygroscopic material that (i) can trap and absorb high quantities of water vapor to prevent heat buildup and subsequent pyrophoric ignition from exothermic oxidation from oxygen, and (ii) can also undergo hydrolysis to produce hydrogen, thus, making it possible to suppress the pyrophoricity without sacrificing the overall hydrogen generation yield of the composite. Lithium hydroxide and lithium borohydride were investigated as two candidate hygroscopic materials for their ability to absorb water vapor.
