Claims
- 1. A method of formulating a gas generant composition comprising the steps of:chilling a predetermined amount of nitric acid to 0-20 degrees Celsius; adding a fuel selected from the group consisting of 5-aminotetrazole, diaminotriazole, azodicarbonamide, hydrazodicarbonamide, semicarbazide, carbohydrazide, biuret, 3,5-diamino-1,2,4-triazole, dicyandiamide, and 3-amino-1,2,4-triazole to the chilled nitric acid thereby forming a mixture wherein the nitric acid is diluted with water and is provided in a molarity and quantity at least sufficient to form a mononitrate of the fuel; adding at least one oxidizer selected from the group consisting of nonmetal, alkali metal, and alkaline earth metal nitrates to the mixture; stirring the mixture to form a wet paste wetted by nitric acid and/or water thereby precipitating a solid solution of the mononitrate of the fuel and the oxidizer; forming the paste into a desired shape; and drying the wet formed paste to remove any residual nitric acid and/or water.
- 2. The method of claim 1 wherein at least one oxidizer is selected from the group consisting of ammonium nitrate, potassium nitrate, and strontium nitrate.
- 3. The method of claim 1 wherein the nitric acid has a molarity of 15.9M or less.
- 4. A method of formulating a gas generant composition comprising the steps of:chilling a predetermined amount of nitric acid to 0-20 degrees Celsius; adding 5-aminotetrazole to the chilled nitric acid to form a slurry, the nitric acid diluted by water and provided in at least a sufficient molarity and quantity to form 5-aminotetrazole nitrate; adding ammonium nitrate and potassium nitrate to the slurry wherein potassium nitrate is about 10% by weight of the combined weight of the ammonium nitrate and the potassium nitrate; stirring the slurry to form a wet paste, thereby forming a solid solution containing 25-95% 5-aminotetrazole nitrate and 5-75% phase stabilized ammonium nitrate; forming the paste into a desired shape; and drying the formed paste to remove any residual nitric acid and/or water.
