ABSTRACT:
A sodium-azide-free gas-generating composition includes an oxidizable borohydride fuel and an oxidizing agent containing oxygen and a metal. The fuel and the oxidizing agent are selected such that water vapor is produced upon reaction between the borohydride fuel and the oxidizing agent. Suitable oxidizing agents contain a metal and oxygen and are selected from a metal oxide, a metal oxide hydrate, a metal oxide hydroxide, a metal hydrous oxide, a metal hydroxide, or mixtures thereof. The fuel and oxidizing agent are selected such that water vapor is the major gaseous combustion product.
