아자이드화나트륨

NaN₃

IUPAC: Sodium azide

CAS: 26628-22-8

개요

Sodium azide is a white crystalline salt that decomposes rapidly when heated, producing nitrogen gas. This property makes it the primary propellant in automotive airbags — when a collision is detected, an electric spark ignites sodium azide, inflating the airbag with N₂ in milliseconds.
