Application:

In photography for making dry plates and light-sensitive papers; manufacture of mineral waters, NH4Br, fire-extinguishing compositions.
Made by the action of hydrobromic acid on calcium oxide and crystallization. The white granular crystals are soluble in water. Calcium bromide was used in making collodion emulsions, particularly for dye-sensitized plates.
Calcium bromide has a number of useful applications. Used in the oil and gas fields, the compound is a true working example. At almost every stage of the oil and gas extraction process, calcium bromide has found extensive usage. Stability, dependability and ease of use distinguish calcium bromide in the drilling process. There, it is used in "drilling muds" worldwide.
