  • Applications

    Xenotime (YPO4), CAS 13817-22-6, is primarily mined as an ore of yttrium and heavy rare earth elements; the material is processed to produce yttrium oxide and other rare-earth oxides used in electronics, notably phosphors and laser materials, and as feedstock for rare-earth separations and refining; its oxides find use in ceramics and specialty glasses as stabilizers and colorants; it supplies high-purity rare-earth chemicals for research and manufacturing; and it supports catalytic formulations and various chemical syntheses in industrial applications.
