Usage

Description

Strontium bromide has the formula SrBr2. At room temperature, it is a white, odorless, crystalline powder with the molecular weight of 247.43 g/mol. Strontium bromide burns bright red in a flame test. It is used in flares and also has some pharmaceutical uses. Several hydrates have been characterized including the monohydrate and the hexahydrate, SrBr2·6H2O. This salt is a white, hygroscopic powder soluble in water and alcohol. It loses water at 180°C, melts at 643°C and is used in medicine and as an analytical reagent. The anhydrate, SrBr2, is a colorless, transparent, crystal, odorless, having a bitter, saline taste. It is very deliquescent and soluble in water and is readily soluble in alcohol and amyl alcohol. The specific gravity of SrBr2 is 4.210 g/cm3. It can be prepared by treating SrCO3 with a hydrogen bromide solution. Alternatively, a strontium salt (carbonate, sulfate, chloride, etc.) is treated with bromine or hydrobromic acid in presence of a reducing agent.

Chemical Properties

White crystalline powder

Uses

Different sources of media describe the Uses of 10476-81-0 differently. You can refer to the following data:
1. Reagent for facile synthesis of poly(phenylcarbyne), a precursor to diamond-like carbon.1
2. Also has some pharmaceutical uses
3. Strontium bromide are colorless crystals made by neutralizing hydrobromic acid with strontium hydrate. The crystals are soluble in water but less so in alcohol. Strontium bromide was occasionally used to increase contrast in collodion emulsions.

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
