Stabilized propellant composition for the generation of nontoxic propellant gases
First Claim
1. A propellant composition for generating nontoxic propellant gases wherein hydrazoic acid is not released, which comprises an alkali azide, an inorganic oxidizing agent, and as the stabilizer for preventing release of hydrazoic acid upon exposure of the composition to humid and carbon dioxide-containing atmosphere, magnesium oxide and/or talc in amounts of between 3 and 10% by weight, based on the weight of the total composition;
- said talc having a MgO content of between 26% and 31.6% by weight.

Abstract
The present invention concerns propellant compositions for the generation of nontoxic gases which are utilized, for example, in airbag generators. These compositions contain, as a gas-yielding component, at least one alkali azide. According to the invention, the compositions are stabilized against the effects of moisture and carbon dioxide by the addition of talc and/or magnesium oxide. These additives are included in amounts of from 3 to 10% by weight. The additive acts so that the propellant compositions do not release hydrazoic acid even under the action of moisture and/or carbon dioxide.
