Chlorate-free autoignition compositions and methods

Chlorate-free autoignition compositions are disclosed, and may be embodied in compositions comprised of (i) an azodiformamidine dinitrate (ADFD), a self-deflagrating, low ignition temperature fuel, (ii) an oxidizer (e.g., a perchlorate, nitrate or mixture thereof) and (iii) an ignition accelerator/augmentor (e.g., a metal or metal oxide powder). One especially preferred solid AIP composition in accordance with the present invention includes ADFD, a mixture of ammonium perchlorate and sodium nitrate, an iron oxide powder and a binder, such as a poly(alkylene carbonate).
