1. For Infrared Spectroscopy & Optical Applications: High-purity potassium bromide (KBr, CAS 7758-02-3) is the standard matrix material for FTIR sample pellets and optical components, providing excellent infrared transparency and low impurity levels for reliable spectroscopic analysis.
2. For Oil & Gas Completion Fluids: KBr is used in clear brine completion and workover fluids, providing precise density control, good thermal stability and corrosion compatibility for well completion operations in oil and gas production.
3. For Photographic Chemicals: As a bromine source in silver halide photographic emulsions, potassium bromide controls emulsion sensitivity and image quality in traditional photographic and imaging applications.
4. For Water Treatment Oxidation: Potassium bromide acts as a bromine source in water treatment systems, supporting oxidation and disinfection processes in cooling water and industrial water treatment applications.
5. For Chemical Intermediates & Laboratory Reagent: KBr serves as a key intermediate for producing silver bromide and other bromide compounds, and is widely used as an analytical reagent in laboratories for titration and testing.
6. Consistent Quality For Global Industry: Supplied as high-purity white crystalline powder or granules with stable assay and consistent quality, potassium bromide gives optical, oilfield, photographic, water-treatment and laboratory customers a dependable bromide salt with flexible packaging and stable supply.
