Abstract: The oxygen generation compositions are tin fueled to produce a significantly lower carbon monoxide contamination of the breathable oxygen generated. The oxygen generating compositions comprise about 0.5-15 % by weight of tin powder as a fuel and rheology modifier; from zero to about 15 % by weight of a transition metal oxide catalyst; about 0.1-5 % by weight of an alkaline compound as a chlorine remover and reaction rate modifier; and the remainder of 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 up to about 5 % of a binder. The oxygen generating compositions have a smoother, more uniform rate of oxygen generation, lower temperature sensitivity, and a lower operating temperature than comparable chlorate/perchlorate oxygen generation compositions utilizing iron powder as a fuel.

Abstract: The oxygen generation composition utilizes magnesium oxide to modify and smooth the oxygen generation rate, suppress chlorine formation, improve the rheology and uniformity of performance of an operating chemical oxygen candle, and to facilitate the mixing of the candle ingredients. The oxygen generation composition typically comprises a metal powder as a fuel; magnesium oxide; and an oxygen source selected from the group consisting of alkali metal chlorates, alkali metal perchlorates, and mixtures thereof. The composition can also include a transition metal oxide catalyst, and can include a binder.

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 of 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.
