Patent ID: 6887326

Claim:
A method of forming a gas generant composition comprising the steps of: mixing dry ammonium nitrate and potassium nitrate in selected amounts in a mixing vessel; adding a high energy primary fuel selected from substituted tetrazoles and substituted bitetrazoles that form naturally occurring hydrates to the mixing vessel; adding water sufficient to dissolve the ammonium nitrate and potassium nitrate; heating and mixing all constituents at about 70-120 degrees Celsius to cook off the surface water; removing the solids from the mixing bowl and granulating the same in a known manner; dehydrating the granulated solids so that the water is less than 1.00% by mass by drying at 90-130 degrees Celsius; band pressing the dehydrated product into the desired geometry, wherein the ammonium nitrate and the potassium nitrate co-precipitate to form phase stabilized ammonium nitrate at 30-90%, and, the primary fuel is at 10-50% after dehydration, said percents given by weight of the total gas generant composition.
