Strontium nitrate is an inorganic compound composed of the elements strontium, nitrogen and oxygen with the formula Sr(NO 3) 2. ... Preparation Strontium nitrate is ...
Strontium nitrate – most common oxidizer/colorant for red colors in flares, fires, and stars; strontium also serves as a stabilizer for the mixtures. [4] At lower temperatures (with organic fuels) produces strontium nitrite ash which can smother the flame; decomposes completely at higher temperatures (with magnesium).
Because Sr(OH) 2 is slightly soluble in cold water, its preparation can be easily carried out by the addition of a strong base such as NaOH or KOH, drop by drop to a solution of any soluble strontium salt, most commonly Sr(NO 3) 2 (strontium nitrate). The Sr(OH) 2 will precipitate out as a fine white powder.
Samarium(III) nitrate is also used for the preparation of samarium doped ceria, which can be used in the fabrication of electrolytes for fuel cells. The samarium doped ceria is produced by mixing cerium(III) nitrate and samarium(III) nitrate together using triethylene glycol as a solvent for 5 hours at 200°C. Then it was dried for 4 hours at ...
Strontium nitrate: Sr(NO 3) 2: Common. Used with chlorine donors. Excellent red, especially with metal fuels. Used in many compositions including road flares. Red Strontium carbonate: SrCO 3: Common. Produces good red. Slows burning of compositions, decomposes yielding carbon dioxide. Fire retardant in gunpowders. Inexpensive, non-hygroscopic ...
Strontium nitride, Sr 3 N 2, is produced by burning strontium metal in air (resulting in a mixture with strontium oxide) or in nitrogen. Like other metal nitrides , it reacts with water to give strontium hydroxide and ammonia:
