Applications by Industry
- Mining & Metals
Ammonium Bifluoride serves metal processors as a pickling agent for stainless steel, supporting the removal of oxide scale from metal surfaces.
- Building & Construction
Ammonium Bifluoride is used in building and construction work for masonry cleaning formulations and glass frosting, where controlled fluoride release is required.
- Oil, Gas & Energy
Ammonium Bifluoride acts as an acidizing additive in oilfield operations, promoting the dissolution of siliceous scales that restrict flow.
Ammonium Bifluoride
Applications
Commonly applied in stainless-steel pickling, glass frosting, and masonry cleaning formulations. In the oilfield sector, it serves as an acidizing additive that promotes dissolution of siliceous scales. It is also an intermediate in fluorine compound synthesis.
Safety & Risks
Highly corrosive and toxic; contact causes severe burns and systemic fluoride poisoning. Generates HF vapors in moisture. Handle only with HF-resistant equipment and PPE, including gloves, face shield, and apron; calcium gluconate gel must be available on-site.
Packaging
Supplied in acid-resistant HDPE drums or plastic-lined steel containers. Store in ventilated, cool areas isolated from bases and oxidizers. Keep containers tightly closed and dry.
