Gas generant composition
First Claim
1. A gas generant composition formed from a method comprising the steps of:
- adding a nitratable base fuel to an excess amount of nitric acid thereby forming a mixture;
adding at least one oxidizer to the mixture;
stirring the mixture to form a homogeneous wet paste;
forming the paste into a desired shape; and
drying the formed paste.

Abstract
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 especially suitable for inflating air bags and actuating seatbelt pretensioners in passenger-restraint devices.
