GENERAL DESCRIPTION & EXTERNAL LINKS
Zinc Bromide is used in photographic processing, as a chemical intermediate for the manufacture of various bromides, rayon and other chemicals. It is used as a completion in oil field drilling applications. Pharmaceutical grade is used in medicine as sedatives.

We calculated the inherent structure of a model melt of zinc (II) bromide over a wide range of densities. Stable, metastable, and unstable branches were obtained for the zero temperature pressure–volume isotherm of the inherent structure. The pressure–volume isotherm, the void distribution, and the structure factor were used to identify the spinodal, independent of any model equation of state......

The bromide form of any metal is generally soluble in water. Bromides are often used when the chloride or nitrate form is hazardous. This has become increasingly the case with the advent of new green chemistry and hazardous materials legislation such as the new REACH program in the European Union. For example, bromides are now being used in many catalytic, electronic, coating and biomedical applications in replacement of other soluble forms for this reason.
Bromide compounds are formed when a metallic cation binds with a charged (- 1) bromine (Br) anion to form a bromide salt of that metal. Bromine is the only liquid halogen. Bromides were first prepared and used as sedatives which is why a "tired" expression or saying is sometimes called a bromide.....Zinc Bromide is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Most metal bromide compounds are water soluble for uses in water treatment, chemical analysis and in ultra high purity for certain crystal growth applications. Bromide in an aqueous solution can be detected by adding carbon disulfide (CS2) and chlorine. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.......
