Abstract
The oxygen generation composition utilizes a catalyst selected from the group consisting of copper oxide, nickel oxide, and mixtures thereof, to catalyze the reaction or a chlorate or perchlorate based oxygen generating composition, smooth oxygen generation, improve the rheology of an operating chemical oxygen candle, and to facilitate the mixing of the candle ingredients. The oxygen generation composition typically comprises about a metal powder as a fuel; a catalyst selected from the group consisting of copper oxide, nickel oxide, and mixtures thereof; an additive as a chlorine remover and reaction rate modifier; and an oxygen source selected from the group consisting of alkali metal chlorates, alkali metal perchlorates, and mixtures thereof. The oxygen generating composition can optionally further include a binder.
