Abstract
The present invention relates to a composition for generating oxygen, comprising at least one oxygen source selected from chlorates and perchlorates, to an oxygen generator comprising such a composition, and a method for generating oxygen by decomposing such a composition. The present invention further relates to the use of zeolite compounds as multifunctional components in the oxygen generating compositions.

A composition for generating oxygen, comprising at least one oxygen source selected from alkali metal chlorates, alkali metal perchlorates, alkaline earth metal chlorates, alkaline earth metal perchlorates and mixtures thereof,
- composition further comprises at least one zeolite compound, the zeolite compound having a framework comprising open channels, and also comprising open cages or closed cages;
- wherein the composition is suitable for use in an oxygen candle and is free from cobalt oxide and manganese oxide and wherein the composition is configured for generating oxygen by a self-sustaining decomposition.
An oxygen generator comprising a composition for generating oxygen by a self-sustaining decomposition, a container for containing the oxygen generating composition, and a primer for starting decomposition of the oxygen generating composition, wherein the oxygen generating composition comprises at least one oxygen source selected from alkali metal chlorates, alkali metal perchlorates, alkaline earth metal chlorates, alkaline earth metal perchlorates and mixtures thereof, wherein the composition further comprises at least one zeolite compound, the zeolite compound having a frame work comprising open channels, and also comprising open cages or closed cages, the composition being suitable for use in an oxygen candle and being free from cobalt oxide and manganese oxide.
