Sodium azide is a versatile precursor to other inorganic azide compounds, e.g., lead azide and silver azide, which are used in detonators as primary explosives. These azides are significantly more sensitive to premature detonation than sodium azide and thus have limited applications. Lead and silver azide can be made via double displacement ...
Sodium azide NaN 3 is the propellant in automobile airbags. It decomposes on heating to give nitrogen gas, which is used to quickly expand the air bag: [ 7 ] 2 NaN 3 → 2 Na + 3 N 2
Older airbag systems contained a mixture of sodium azide (NaN 3), KNO 3, and SiO 2. A typical driver-side airbag contains approximately 50–80 g of NaN 3, with the larger passenger-side airbag containing about 250 g. Within about 40 milliseconds of impact, all these components react in three separate reactions that produce nitrogen gas.
To be removed from the dangers of airbag deployment, dogs should be kept in the backseat and restrained by a harness. ... The electrical charge from the accident sensor to the sodium azide takes 2 ...
Compounds such as sodium azide – which has ionic character – tend to be less sensitive, [1] Such compounds are relevant to high-energy-density matter. [4] [5] although sodium azide is, ironically, the principal gas-forming component of air bags. It is the most important azide from a commercial perspective.
The company also produced a number of the earliest practical airbag systems, building the high-speed sodium azide exothermic gas generators used to inflate the bags. Thiokol bags were first used in U.S. military aircraft, before being adapted to space exploration ( Mars Pathfinder bounced down on Mars on Thiokol airbags) [ citation needed ] and ...
Sodium azide had gone through a rigorous examination of over 15 potential airbag inflation technologies in the late 1970s after the weaknesses in the GM system had been demonstrated. Sodium Azide and a correctly designed inflator and module design was superior to other stored gas, heated stored gas or organic propellants.
Sodium azide, older, highly stable airbag propellant phased out by Takata in the 1990s in favor of the less potentially toxic tetrazole Guanidine nitrate , alternative airbag propellant used in Autoliv and TRW airbags, less sensitive to moisture [ 62 ]
