Strontium nitrate

Strontium nitrate (CAS 10042-76-9) is an inorganic salt supplying both strontium and nitrate ions to industrial formulations and pyrotechnic compositions.

Where is Strontium nitrate used?

• Pyrotechnics and defense: oxidizing agent in red signal flares and tracer ammunition
• Military illumination rounds: consistent burn characteristics as a qualification requirement
• Automotive airbag inflators: oxidizer component in gas-generating propellant mixtures
• Aerospace aluminum: active pigment in corrosion-inhibiting primers
• Coatings: replacement for chromate-based systems in compliant formulations
• Textile and paper: specialty flame-retardant treatments requiring halogen-free chemistry
• It is the primary oxidizer responsible for producing a characteristic crimson flame in signal flares and fireworks.

Commercial specifications

• Technical grade, purity typically 99% to 99.5% on a dry basis
• Bags and bulk quantities for industrial-scale consumption
