ABSTRACT:
A relatively low temperature nitrogen gas generating composition is disclosed which consists essentially of (a) from about 10 to about 50 percent by weight of an oxidizer selected from the oxides of iron, nickel and cobalt, said oxidizer having a primary particle size in the range from about 0.1 micron to about 7 microns in diameter; and, (b) at least 50 percent by weight of an alkali metal azide. Optionally, less than about 10 percent by weight of an alkali metal perchlorate may be included as a booster. The nitrogen gas generating composition provides the nitrogen gas at a low enough temperature but at a sufficiently high speed, without generating a large quantity of finely divided solid residue particles. A major portion of the combustion residue is a coherent porous solid sinter or fused mass of residue particles which autogenously provides both self-filtration of ejected particles and sorption of any molten combustion product.
