Disclosed is a heat-treated oxidizing agent for gas generating compositions which is obtained by mixing ammonium nitrate with an inorganic compound having as an element one or two or more metal atoms selected from the group consisting of Cu, Fe, Ni, Zn, Co, Mn and Ti and subjecting the mixture to heat treatment, and a gas generating composition containing the same. This invention provides a gas generating composition comprising ammonium nitrate, which can be safely produced, does not change in density with phase transition, and has sufficient combustibility.

Gas generating composition

A gas generator, including an igniter, a gas generating agent ignited by the igniter and generating gas by burning, and a holder and an AC cup forming therein a gas generating agent storage chamber filled with the gas generating agent. A housing formed of the holder and the AC cup is vertically held and fixed by a pair of plate-like members arranged parallel with each other. The gas generator also includes projections forming deformable areas which are deformed in a direction for decreasing the vertical outside dimensions of the gas generator when the housing is fixed by the pair of plate-like members. Thus, when the gas generator is fixed by the pair of plate-like members in the vertical direction, the dispersion of the outside dimensions of the gas generator can be absorbed.

Gas generator

A micro gas generator with an automatic ignition function operated before being weakened by heat without impairing the cleanliness of exhaust gas, comprising gas generating agent, a cup body for filling the gas generating agent therein, and a holder formed integrally with squibs and fixedly sealing the squibs in the cup body, wherein an automatic igniting agent layer is put on the inner surface of the cup body.

The present invention provides a gas generant composition comprising a nitrogen-containing organic compound, an oxidizing agent and an additive, wherein a calorific value per mol of gas generated by the combustion of the gas generant is not more than 125 KJ. Also, the present invention provides a gas generator using the said gas generant composition of the present invention. In the gas generant composition that burns at a suitable combustion speed for the gas generator, a calorific value per mol of gas generated by the combustion of the gas generant is suppressed to a specific value as noted above, whereby reduction in size and weight of the gas generator is achieved.

Gas-generating agent composition and gas generator employing the same

A gas generating composition which contains a nitrogenous organic compound as a fuel component and generates, at a high gasification rate, a clean gas harmless to the human body. The composition of the present invention comprises a nitrogenous organic compound as a fuel component and ammonium perchlorate and the nitrate of an alkaline metal or alkaline earth metal as oxidizing agents, wherein where a quantity of nitrate required solely for forming an oxide of alkaline metal or alkaline earth metal that can stoichiometrically neutralize hydrogen chloride generated from ammonium perchlorate is taken as 1, a quantity of nitrate of said alkaline metal or alkaline earth metal exceeds 0.9.
