Abstract
The oxygen generation compositions include about 0.5-15% by weight of a substantially carbon-free metal fuel, and about 0.1-20% by weight of alkali metal silicate, stannate, titanate or zirconate as a reaction rate and core rheology modifier and chlorine suppresser. The oxygen generating compositions also contain about 0.1-15% by weight of a transition metal oxide catalyst; and the remainder is substantially an alkali metal chlorate or perchlorate.
Claims6
In an oxygen generating composition for producing a breathable oxygen gas upon ignition of the composition, the oxygen generating composition comprising about 0.5-15% by weight of a metal fuel;
- about 0.1% to about 15% by weight of at least one transition metal oxide catalyst;
- about 0.1 to about 20% by weight of an additive selected from the group consisting of an alkali metal silicate, an alkali metal stannate, an alkali metal titanate, an alkali metal zirconate, and mixtures thereof;
- and the remainder substantially comprising an oxygen source selected from the group consisting of alkali metal chlorates, alkali metal perchlorates, and mixtures thereof, the improvement wherein said metal fuel is substantially carbon-free copper.
