Abstract
A low-solids gas generating composition and a method of generating a gas with low solids by preparing and combusting the low-solids gas generating composition. The compositions of the invention include a mixture of a basic copper nitrate oxidizer and a fuel selected for the group consisting of 5-nitro-uracil, guanidine 5-nitro-uracil salt, ammonium 5-nitro-uracil salt, aminoguanidine 5-nitro-uracil salt, hydrazine 5-nitro-uracil salt, triamino 5-nitro-uracil salt, guanidine 5-nitro-barbituric acid salt, ammonium 5-nitro-barbituric acid salt, hydrazine 5-nitro-barbituric acid salt, aminoguanidine 5-nitro-barbituric acid salt, triaminoguanidine 5-nitro-barbituric acid salt, and mixtures thereof, wherein the oxidizer-fuel mixture is within about 4 percent of stoichiometric balance, and produces no more than about 0.06 cubic centimeters of solids per gram of gas generating composition on combustion. The compositions of the invention may further include at least one of cupric oxalate hemi-hydrate, sub-micron fumed silica, and graphite.
