Specifications Item Technical Grade Medical Grade Appearance White Crystal`line Solid White crystal`line Solid Assay (as NaBr) 98.5 Percent min. 99 Percent min. Loss on Drying 1 Percent max. 0.5 Percent max. Chloride 1.0 Percent max. 0.5 Percent max. Sulphate 0.05 Percent max. 0.02 Percent max. pH (5 Percent solution) 5.5 – 9.5 5.5-9.5 3. Applications:Sodium Bromide is used as a completion and work over fluid either by itself or with sodium chloride, potassium chloride or bromide, or with zinc bromide. Its main advantage is in formations containing carbonate and/or sulfate ions which give rise to precipitation in the presence of other multivalent completion or work over fluids. Depending on the fluid composition and the required crystal`lization temperature, solutions of up to 12.5 ppg (1.5 gr/ml) NaBr/NaCl or 19.2 ppg (2.3 gr/ml) NaBr/ZnBr2 can be prepared.. It can also be used as water treatment in pool spa, nerve ataractic in medicine` etc. 4.
