Used as a flame retardant in ceramics and glass manufacturing due to its ability to enhance thermal stability and reduce flammability. It also serves as a corrosion-inhibiting pigment in coatings and primers, especially in industrial paints for metal protection. In some specialized applications, it functions as a component in dental cements and restorative materials, contributing to setting properties and durability. Additionally, it is employed in the production of electronic ceramics where controlled phosphate content is required for performance.
