Preferred gas generant compositions incorporate a combination of 5-aminotetrazole nitrate and an oxidizer. The oxidizer may be selected from a group including nonmetal and metal nitrates, nitrites, chlorates, chlorites, perchlorates, and oxides. 5-aminotetrazole nitrate is characterized as an oxygen-rich fuel and is therefore considered to be a self-deflagrating fuel. To tailor the oxygen balance in certain applications, however, the use of an oxidizer is preferred. Methods of formulating the compositions are also described. These compositions are especi...


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 mo...
