Calcium bromide (CaBr2) is a chemical compound of calcium and bromine. In its solid state, it is a white powder. CaBr2 can be found in drilling fluids, neuroses medication, freezing mixtures, food preservatives, photography and fire retardants.[1]
When strongly heated in air, calcium bromide will produce calcium oxide and bromine.
- 2 CaBr2 + O2 → 2 CaO + 2 Br2
