Ammonium fluoride is widely used in the glass etching industry to create frosted or matte finishes on glass surfaces. It is also employed in metal treatment processes, particularly for cleaning and etching aluminum and other metals before further processing or coating. In the electronics industry, it serves as a component in the production of semiconductors and integrated circuits, where it aids in cleaning and etching silicon wafers. Additionally, it is used in wood preservation treatments to protect against fungi and insects. In analytical chemistry, ammonium fluoride acts as a buffering agent and is utilized in certain types of spectroscopy. Its applications extend to the manufacturing of ceramics and as a flux in soldering processes.
