Strontium nitrate Chemical Properties,Uses,Production

Chemical Properties

Colorless cubic crystals or white powder or granules; density 2.986 g/cm3; melts at 570°C; very soluble in water, 80 g/100 mL at 18°C; very slightly soluble in ethanol.
The tetrahydrate constitutes colorless monoclinic crystals; density 2.20 g/cm3; loses all water of crystallization at 100°C; converts to strontium oxide, SrO at 1,100°C; very soluble in water, 60.4g/100 mL at 0°C, 206 g/100 mL at 100°C; soluble in liquid ammonia; very slightly soluble in ethanol and acetone.

Chemical Properties

Strontium nitrate is a white crystalline solid

Uses

Strontium nitrate [Sr(NO3)2], because of the bright red flame it produces when burned, is used in fireworks, matches, marine signals, and so forth.

Uses

Used in preparation of strontium standard solutions

Uses

Strontium nitrate is used in pyrotechnics, for producing marine and railroad signals, and in matches.

Uses

In pyrotechnics (red fire), signal lights, marine signals, railroad flares, matches.

Preparation

Strontium nitrate is prepared by treating strontium carbonate with nitric acid. The solution is evaporated and crystallized:
SrCO3 + HNO3 → Sr(NO3)2 + CO2 + H2O
Crystallization yields the tetrahydrate, Sr(NO3)2•4H2O, which on heating dehydrates to form the anhydrous nitrate.

brand name

Strotope (Bristol-Myers Squibb).

General Description

A white crystalline solid. Noncombustible but accelerates burning of combustible materials. May explode if large quantities are involved in a fire or the combustible material is finely divided. May explode under prolonged exposure to heat or fire. Toxic oxides of nitrogen are produced in fires. Used in pyrotechnics, in medicine, and to make other chemicals.

Air & Water Reactions

Soluble in water.

Reactivity Profile

Mixtures of metal/nonmetal nitrates with alkyl esters may explode, owing to the formation of alkyl nitrates; mixtures a nitrate with phosphorus, tin (II) chloride, or other reducing agents may react explosively [Bretherick 1979 p. 108-109]. Special Hazards of Combustion Products: Yields toxic gaseous oxides of nitrogen when involved in fire.

Health Hazard

Dust is irritating to skin, eyes, and respiratory system.

Safety Profile

Moderately toxic by ingestion and intraperitoneal routes. A powerful oxidizer. When heated to decomposition it emits toxic fumes of NOx.See also NITRATES and STRONTIUM COMPOUNDS.

Potential Exposure

Strontium nitrate is used in matches, pyrotechnics, marine signals; and railroad flares.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 hours in case chemical pneumonia or other respiratory symptoms are present.

Shipping

UN1507 Strontium nitrate, Hazard Class: 5.1; Labels: 5.1-Oxidizer.

Purification Methods

Crystallise it from hot water (0.5mL/g) by cooling to 0o.

Incompatibilities

A strong oxidizer. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Violent reaction with reducing agents; combustibles, organics, or other readily oxidizable materials. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
