The gas generating composition of the invention contains an oxide-based catalyst comprising at least two members selected from the elements of Groups I, IV, V, VI, VII and VIII in the periodic table in addition to the nitrogen-containing organic compound and the oxygen-containing inorganic oxidizing agent both essentially incorporated in the gas generating composition. The invention also provides a process for molding a gas generating composition, the process comprising the steps of adding 5 to 20% by weight of water to a gas generating composition essen...


[ What we claim is:] [1.] A gas generating composition consisting essentially of an azodicarbonamide, an oxygen-containing inorganic oxidizing agent, and an oxide-based catalyst consisting essentially of at least one member selected from the group consisting of Co, Li, Na, K, Rb, Cs, Ag, Cu, Sn, Pb, V, As, Sb, Bi, Fe and Ni salts of molybdic acid, chromic acid and tungstic acid, the amount of the oxidizing agent being at least the stoichiometric amount necessary for oxidizing the azodicarbonamide.
