Ammonium bifluoride is widely used in various industrial applications due to its unique properties. It is commonly employed in glass etching and frosting processes, where it helps create decorative or functional designs on glass surfaces. In the metal industry, it serves as a cleaning agent to remove oxides and impurities from metal surfaces, particularly in aluminum and stainless steel treatment. It is also utilized in the production of ceramics and as a component in certain cleaning products for industrial equipment. Additionally, it plays a role in the petroleum industry as a catalyst in oil refining processes. Its ability to react with silica makes it useful in the manufacturing of electronics and semiconductors for etching silicon wafers. However, due to its corrosive nature, it requires careful handling and appropriate safety measures during use.
