Used in dental materials, particularly in toothpaste formulations designed for sensitive teeth. It helps block exposed dentinal tubules, reducing pain from thermal or mechanical stimuli. Also used in the ceramic industry and coatings due to its thermal stability and ability to improve material properties such as strength and corrosion resistance. Investigated for use in bone cements and bioceramics due to its biocompatibility and ability to support bone tissue regeneration. Serves as a precursor in the synthesis of luminescent materials and phosphors for LEDs and display technologies. Occasionally used in analytical chemistry as a reagent for phosphate detection and separation processes.
