Characteristic
Barium bromide is the chemical compound with the formula BaBr2. Like barium chloride, it dissolves well in water and is toxic.
Chemical formula：BaBr2 (anhydrous)
BaBr2·2H2O (dihydrate)
Molar mass：297.14 g/mol
Appearance：White solid
Density：4.78 g/cm3 (anhydrous)
3.58 g/cm3 (dihydrate)
Melting point：857 °C (1,575 °F; 1,130 K)
Boiling point：1,835 °C (3,335 °F; 2,108 K)
Solubility in water：92.2 g/100 mL (0°C)
Magnetic susceptibility (χ)：-92.0·10−6 cm3/mol
Crystal structure：orthorhombic, oP12
Application
Barium bromide is a precursor to chemicals used in photography and to other bromides.
Historically, barium bromide was used to purify radium in a process of fractional crystallization devised by Marie Curie. Since radium precipitates preferentially in a solution of barium bromide, the ratio of radium to barium in the precipitate would be higher than the ratio in the solution.
