There is provided a gas generating composition consisting essentially of a mixture of nitroguanidine and phase stabilized ammonium nitrate. When the ammonium nitrate is phase stabilized with from about 7% to about 20%, by weight, of a potassium salt, the mixture is structurally and volumetrically stable over typical automotive operating temperatures and has a melting temperature in excess of 100°C. The mixture generates large volumes of nitrogen and carbon dioxide when ignited with minimal generation of solids or toxic gases and is particularly useful as...
