Zinc bromide is a high-purity inorganic compound widely utilized to formulate high-density clear brines for oilfield completion and workover operations. Its exceptional solubility allows for the creation of heavy fluids essential for maintaining wellbore stability and pressure control in deep, high-pressure wells.
Functioning as a potent Lewis acid, this chemical serves as a critical catalyst in organic synthesis and industrial chemical manufacturing processes. It is also a key electrolyte component in zinc-bromine flow batteries, providing efficient, scalable energy storage solutions for modern renewable grids.
Our product is available in both brine solution and anhydrous powder forms to suit diverse radiation shielding and viewing window applications. We ensure strict quality control to deliver optimal specific gravity and low contaminant levels, meeting the rigorous demands of the energy sector.

Zinc bromide
Applications
- Oilfield Completion Fluids:Used to create high-density brines that control formation pressures and prevent well blowouts during completion and workover.
- Energy Storage: Acts as the primary electrolyte in zinc-bromine flow batteries for stationary energy storage systems.
- Chemical Synthesis: Serves as a Lewis acid catalyst in Friedel-Crafts alkylation and other organic reactions.
- Radiation Shielding: Employed in the manufacturing of viewing windows for nuclear shields due to its high density and optical clarity.
Safety & Risks
Zinc bromide is classified as Corrosive and an Environmental Hazard. Direct contact can cause severe skin burns and eye damage; it is also toxic to aquatic life with long-lasting effects. Handlers must wear full chemical-resistant PPE, including safety goggles, face shields, and impervious gloves. Ensure adequate ventilation and avoid release into water systems.
