Usage

Description

Strontium bromide, with the chemical formula SrBr2, is a white, odorless, crystalline powder at room temperature. It has a molecular weight of 247.43 g/mol and exhibits a bright red color in a flame test. Strontium bromide is hygroscopic, soluble in water and alcohol, and is used in various applications, including pharmaceuticals and as an analytical reagent.

Uses

Used in Flare Production:
Strontium bromide is used as a component in flares for its bright red color emission during combustion, which aids in visibility and signaling.
Used in Pharmaceutical Applications:
Strontium bromide serves as a pharmaceutical ingredient due to its unique properties, which can be beneficial in the development and formulation of certain medications.
Used as an Analytical Reagent:
In the field of chemistry, strontium bromide is utilized as a reagent, particularly for the facile synthesis of poly(phenylcarbyne), a precursor to diamond-like carbon.
Used in Collodion Emulsions:
Historically, strontium bromide was occasionally used to increase contrast in collodion emulsions, although this application is less common today.
Chemical Properties:
Strontium bromide is a white crystalline powder that is very deliquescent and has a specific gravity of 4.210 g/cm3. It can be prepared by treating strontium carbonate (SrCO3) with a hydrogen bromide solution or by reacting a strontium salt with bromine or hydrobromic acid in the presence of a reducing agent.

Hazard

Toxic by ingestion and inhalation.

Purification Methods

Crystallise the bromide from water (0.5mL/g). It is deliquescent. [Ehrlich in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 930 1963.]

Synthesis and structural characterization of new phases in the cubic M 3Te2O6X2 (M = Sr, Ba; X = Cl, Br) structure family

Four alkaline earth oxotellurate(IV) halides with common formula M 3Te2O6X2 (M = Sr, Ba; X = Cl, Br) have been prepared as polycrystalline powders and/or in the form of single crystals. All compounds crystallize in the cubic space group Fd (3) m with cell parameters a = 15.9351(4) A for Sr3Te2O 6Cl2 (single-crystal X-ray data), 16.052(5) A for Sr3Te2O6Br2 (powder X-ray data), 16.688(2) A for Ba3Te2O6Cl2 (single-crystal X-ray data) and 16.8072(3) A for Ba3Te 2O6Br1.64Cl0.36 (single-crystal X-ray data). The results of the crystal structure analyses reveal a rigid (3)[M3Te2O6]2+ framework which can be described as being composed of regular octahedra of two types of chemically non-bonded M6 octahedra that are capped by trigonal pyramidal [TeO3] anions located above every second face of one of the M 6 octahedra. The halide X- anions are situated in the voids of the [M3Te2O6]2+ framework. Dependent on the nature of the halogen, the anions show various kinds of occupational disorder which eventually led to a revision of the previous structure model of Ba3Te2O6Cl2. A comparative discussion with other structures of general formula M 3Ch2O6X2 (M = divalent metal; Ch = Te, Se; X = Cl, Br) is presented. Copyright
