Calcium bromide is the calcium salt of hydrobromic acid with the chemical formula of CaBr2. It is a white powder that reacts with water to form the hexahydrate. CaBr2 is mainly used in drilling fluid.

Uses
It is mainly used as dense aqueous solutions for drilling fluids. It is also used in neuroses medication, freezing mixtures, food preservatives, photography and fire retardants.
It is produced by the reaction of calcium oxide, calcium carbonate with hydrobromic acid or the reaction of calcium metal with elemental bromine.
It adopts the rutile structure, featuring octahedral Ca centres bound to six bromide anions, which also bridge to other Ca centres.
In this reaction the oxygen oxidizes the bromide to bromine.
