SrNO32

SrNO32 refers to strontium nitrate, Sr(NO3)2. It is an inorganic compound formed from strontium cations (Sr2+) and two nitrate anions (NO3−). At room temperature it appears as white, odorless crystals and is highly soluble in water.

As an oxidizing salt, strontium nitrate participates in combustion processes and can release nitrogen dioxide and oxygen when heated. Its thermal decomposition is typically represented by the reaction 2 Sr(NO3)2 → 2 SrO + 4 NO2 + O2.

Production and purification are industrially straightforward. Strontium nitrate is obtained by neutralizing a strontium base, such as strontium carbonate (SrCO3) or strontium hydroxide (Sr(OH)2), with nitric acid (HNO3), followed by crystallization and drying to yield a pure solid.

Applications concentrate on its role as an oxidizer and colorant aid. In pyrotechnics and signaling, strontium nitrate is valued for producing a characteristic crimson flame. It is also used to color glass and ceramics and can serve as a laboratory oxidizer in certain chemical reactions.

Safety considerations are important due to its oxidizing properties. As with other nitrates, it can intensify fires and should be kept away from organic materials and strong reducing agents. Direct exposure may irritate the skin, eyes, and respiratory tract; handling should use appropriate protective equipment and storage in a cool, dry place.
