Abstract
An on-demand system for generating Iodine gas that is substantially free of contaminants such as water, Carbon Monoxide and Carbon Dioxide includes a solid mixture of oxidizer and fuel having at least one Iodine compound. An ignitor squib is provided to ignite the mixture and thereby generate a contaminant free Iodine gas. Preferably, Iodine Pentoxide (I2O5) is used as the oxidizer and a metal such as Zinc, Tin, Calcium, Magnesium, Aluminum, Silica, Sodium, Potassium, Lithium, Boron, Beryllium, Sodium Azide or Iron is used as the fuel. With this composition, the solid mixture is substantially free of Hydrogen and Carbon compounds and the corresponding combustion gas is free of water, Carbon Monoxide and Carbon Dioxide. The mixture is disposed within a permeable jacket to capture non-gas reaction products generated during combustion such as solid and liquid metal oxides while allowing Iodine gas to pass through the permeable jacket.
