Abstract
The autoignition compositions of the present invention ignites in the temperature range of 120° C. to 160° C. The autoignition compositions are thermally stable at 107° C. for 400 hours and are thermally stable during thermal cycling. The preferred composition for the autoignition composition comprises equal weight percentages of the following chemicals: nitroguanidine, Sb2S3, and AgNO3. An ignition temperature adjuster selected from the group consisting of teflon powder, graphite powder, ammonium perchlorate, MoS2, and FeS can be added to the preferred autoignition composition.
Claims4
An autoignition composition for use in a gas generating device comprising:
- a) a fuel at 20-60% by weight selected from a group consisting of nitroguanidine, aminotetrazoles, tetrazoles, bitetrazoles, and nitrates;
- b) a transition metal sulfide at 20-60% by weight, and
- c) an oxidizer at 20-60% by weight selected from the group consisting of metal nitrates and nitrites.
