ABSTRACT:
The chlorate/perchlorate based oxygen generating compositions contain about 0.5-15% by weight of metal powder for use as a fuel selected from the group consisting of iron, nickel, cobalt and mixtures thereof; about 0.1% to about 15% by weight of at least one transition metal oxide catalyst; greater than 5% to about 25% by weight of an alkali metal silicate as a reaction rate and core rheology modifier, binder and chlorine suppresser; and the remainder substantially comprising an oxygen source selected from the group consisting of alkali metal chlorates, alkali metal perchlorates, and mixtures thereof. The alkali metal silicate can be selected from the group consisting of sodium metasilicate, sodium orthosilicate, lithium metasilicate, potassium silicate, and mixtures thereof. The oxygen generating composition can also optionally contain a binder selected from the group consisting of glass powder, fiber glass and mixtures thereof.
