1. 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
about 50 to about 99.3% by weight of 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.

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.
