Usage

Description

Barium bromide is an inorganic compound with the chemical formula BaBr2. It is a white crystalline solid that is highly soluble in water and has a high refractive index. Barium bromide is commonly used in various applications due to its unique properties, such as its high solubility, high refractive index, and its ability to form complexes with other compounds.

Uses

Used in Chemical Industry:
Barium bromide is used as a precursor to chemicals used in the manufacturing of bromides, photographic compounds, and phosphors. It is also used in the production of zinc bromide.
Used in Radiography:
Barium bromide dihydrate is used to purify radium, which is an important application in the field of radiography. It helps in obtaining high-purity radium, which is essential for various radiographic applications.
Used in Photography:
Barium bromide is used as a precursor to chemicals used in photography. It plays a crucial role in the development of photographic films and papers, as it helps in the formation of the light-sensitive emulsion layers.

Hazard

A poison.

Purification Methods

It crystallises from H2O (1mL/g) by partial evaporation in a desiccator. [Ehrlich in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 930 1963.]
