Zinc bromide Usage
-
Oilfield Completion & Workover Fluids:
-
Used as a high-density, solids-free clear brine completion, workover, and packer fluid in deep oil and gas wells. Prevents formation damage and controls downhole pressure safely.
-
-
Energy Storage & Zinc-Bromine Flow Batteries:
-
Functions as a key electrolyte salt in advanced zinc-bromine flow batteries for large-scale energy storage system (ESS) applications.
-
-
Organic Synthesis & Catalyst:
-
Serves as a Lewis acid catalyst in organic transformations, including stereoselective synthesis, Friedel-Crafts alkylations, and protective group chemistry.
-
-
Pharmaceutical Intermediates & Radiation Shielding:
-
Used in pharmaceutical active ingredient (API) synthesis and as a transparent optical liquid window for radiation shielding in nuclear laboratories.
-
-
Photography industry:
-
Used for the preparation of photographic colloidal emulsions.
