Strontium Nitrate
Sr(NO₃)₂ | CAS: 10042-76-9 | HS: 28342990
Product Description
Strontium Nitrate is the primary oxidising agent responsible for the vivid crimson-red colour in pyrotechnics, military signal flares, railway detonators, and marine distress signals. As one of the most internationally traded strontium salts, it is a critical input for fireworks manufacturers across Europe, Southeast Asia, and Latin America. MITCHEM supplies pyrotechnic and technical grades with full oxidising materials compliance packaging, UN classification documentation, and MSDS for seamless export clearance.
Applications by Industry
The oxidiser of choice for red-colour pyrotechnic compositions; decomposes to release oxygen and strontium ions that emit characteristic crimson light at ~650 nm wavelength.
Used in illuminating and signal flares for railway, marine, and defence applications where a reliable, bright red colour signal is required across long distances.
Acts as a source of strontium oxide in specialty optical glass formulations, improving refractive index and density.
Combined with fuel and binder in star compositions for aerial shells, roman candles, and ground effects producing red stars and effects.
