Strontium dinitrate

Strontium dinitrate is an inorganic chemical compound with the molecular formula N2O6Sr and CAS number 10042-76-9. This salt consists of strontium cations combined with nitrate anions, resulting in a white crystalline solid with a molecular weight of 211.63 g/mol. It belongs to the family of alkaline earth metal nitrates and exhibits oxidizing properties due to its nitrate content.

Strontium dinitrate appears as a white crystalline powder that is highly soluble in water and slightly soluble in alcohol. The compound is odorless and hygroscopic, meaning it readily absorbs moisture from air. It has a density of approximately 2.99 g/cm³ and decomposes at elevated temperatures rather than melting, releasing oxygen and forming strontium oxide.

Strontium dinitrate is primarily used in pyrotechnics and fireworks manufacturing to produce brilliant red flames and colors. It serves as an oxidizing agent in various chemical reactions and is utilized in the production of other strontium compounds. The compound also finds applications in signal flares, tracer ammunition, and specialized ceramic formulations where strontium incorporation is required.

Strontium dinitrate should be handled with standard chemical safety precautions including wearing safety goggles, gloves, and protective clothing. Work in well-ventilated areas to avoid dust inhalation and use appropriate respiratory protection when necessary. As an oxidizing agent, keep it away from combustible materials, reducing agents, and heat sources to prevent potential fire or explosive hazards.

Strontium dinitrate must be stored in a cool, dry place in tightly sealed containers to prevent moisture absorption. Keep separated from incompatible materials including combustible substances, organic compounds, metals, and reducing agents. Storage areas should be well-ventilated and away from heat sources, ignition sources, and direct sunlight to maintain product stability and prevent hazardous reactions.

Strontium dinitrate exposure requires immediate action: for skin contact, wash thoroughly with soap and water; for eye contact, rinse immediately with plenty of clean water for at least 15 minutes; if inhaled, move to fresh air immediately. Remove contaminated clothing and wash before reuse. Seek medical attention if irritation persists or if large quantities have been ingested or inhaled.

Strontium dinitrate disposal must comply with local and national hazardous waste regulations as it is classified as an oxidizing substance. Contact licensed waste disposal companies specialized in chemical waste management. Do not dispose of in regular trash, sewers, or waterways. Small quantities may require neutralization or special treatment before disposal, following environmental protection guidelines.

Strontium dinitrate is classified under ADR Class 5.1 (Oxidizing substances) Packing Group III for transportation. It must be packaged in approved containers with proper hazard labels and documentation. Transport vehicles require appropriate placarding and drivers need ADR certification. The compound should be segregated from incompatible materials during transit and handled according to dangerous goods transportation regulations.

Strontium dinitrate is regulated under various chemical safety frameworks including REACH registration requirements in Europe. It is not classified as a Substance of Very High Concern (SVHC) and currently has no specific GHS hazard classifications. However, users must comply with general chemical safety regulations, workplace exposure limits, and proper labeling requirements according to regional legislation.
