Question: An industrial concern has experimented with several different mixtures of the four components – magnesium, sodium nitrate, strontium nitrate, and a binder – that comprise a rocket propellant. The company has found that two mixtures in particular give higher flare-illumination values than the others. Mixture 1 consists of a blend composed of the …Web
All you need is a suitable metal salt and a fuel: Strontium or lithium salt. Clean-burning fuel. Strontium and lithium salts produce red flames. Strontium, in the form of strontium nitrate or strontium chloride, yields the red color seen in emergency flares and red fireworks. Lithium chloride produces a vivid reddish-violet or pink flame.Web

The 3110 propellant components are strontium nitrate, 5-amino-1H-tetrazole (5-AT), potassium salt of 5-amino-1H-tetrazole (K5-AT) and clay. BHT, 5-AT and K5-AT act as fuel, while AN, KN and SrN act as oxidizer. Clay is used as a combustion modifier. Ammonium nitrate is used in fertilizers, industrial explosives, rocket propellants and pyrotechnics.Web
Strontium nitrate is utilized in flares and pyrotechnic devices because it burns with an intense red flame.

When we cook the composition (red fire) in the water is obtained, strontium nitrate solution (solute) in water. Then dry the stars and strontium nitrate crystallizes. If dry stars below 32C, then formed Sr (NO3)2*4H2O. If dry stars at temperatures above 32C, formed Sr (NO3)2. P.S. Sorry for my english.Web
Strontium nitrate is widely used as a component of pyrotechnic compounds for signals, lighting, and incendiary rockets. It colors the flame carmine-red. Although all strontium compounds stain the flame in the same color, strontium nitrate is preferable for pyrotechnics because it also works as an oxidizing agent.Web
