Used as a corrosion inhibitor in metal surface treatment processes, particularly for aluminum and aluminum alloys. It forms a protective conversion coating that enhances paint adhesion and improves resistance to environmental degradation. Commonly applied in aerospace and automotive industries where durable, lightweight metal components require long-term protection against moisture and oxidation. Also utilized in ceramic glazes and glass manufacturing as a fluxing agent to improve hardness and thermal stability. Finds use in some flame-retardant materials due to its ability to promote char formation in polymers.
