Used as a flame retardant in plastics and textiles due to its ability to release water and form protective glassy layers when heated. Also serves as a corrosion inhibitor in coatings and industrial water systems by forming protective films on metal surfaces. Employed in ceramics and glass manufacturing to improve thermal stability and chemical resistance. Acts as a precursor in the synthesis of phosphors and electronic materials. Occasionally used in analytical chemistry as a reagent for phosphate detection and separation processes.
