· Na1 N3

Sodium azide (NaN₃) is an inorganic ionic ceramic compound composed of sodium cations and azide anions. While primarily known as a chemical reagent and safety component, it functions as a brittle ceramic material with moderate stiffness characteristics. This compound is notable for its role in automotive airbag systems and explosive/pyrotechnic applications, where its rapid decomposition under thermal or mechanical stimulus is engineered to produce inert nitrogen gas—a property that distinguishes it from conventional structural ceramics and makes it valuable in safety-critical triggering systems.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
