초록

The present invention relates to an autoignition composition for safely initiating combustion of a main pyrotechnic charge in a gas generator or pyrotechnic device exposed to flame or a high temperature environment. The autoignition compositions of the invention include a mixture of an oxidizer composition and a powdered metal, wherein the oxidizer composition includes at least one of an alkali metal or an alkaline earth metal nitrate, a complex salt nitrate, such as Ce(NH.sub.4).sub.2 (NO.sub.3).sub.6 or ZrO(NO.sub.3).sub.2, a dried, hydrated nitrate, s...
