Abstract
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.
Claims25
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 combustion of the gas generant is not more than 125 KJ, and
- wherein the nitrogen-containing organic compound is selected from tetrazoles, guanidine, derivatives of guanidine, salts thereof, or mixtures thereof, and
- wherein the oxidizing agent is a mixed oxidizing agent comprising basic copper nitrate and at least one material selected from the group consisting of nitrate salt of alkaline earth metal and phased stabilized ammonium nitrate, and
- wherein the additive is selected from silicon nitride, silicon carbide, silicate, organic silicon compounds, binder compounds, lubricants, combustion adjusters, or mixtures thereof.
