Abstract
The oxygen generating compositions contain carbon-free metal powder as fuel to minimize generation of carbon monoxide. The carbon-free metal powder can be selected from copper, zinc, and antimony, and mixtures thereof, and can be used in combination with tin or iron. The oxygen generating compositions produce a breathable gas upon ignition of the composition, and comprise about 1-15% by dry weight of the metal powder as a fuel; about 0.1-5% by dry weight of at least one alkaline compound; a transition metal oxide catalyst; and the remainder substantially comprising an oxygen source. The oxygen generating compositions can optionally include a binder. An oxygen generating candle can also have an ignition pellet having a composition of about 25-50% by weight copper, zinc or antimony, 5-20% by weight Co.sub.3 O.sub.4, about 2-5% by weight glass powder, 0-25% by weight KClO.sub.4, and the balance being substantially NaClO.sub.3.
