Used as a precursor in the synthesis of yttrium-based ceramic materials and phosphors for lighting and display technologies. Employed in the preparation of catalysts for organic transformations and polymerization reactions. Applied in coating formulations to produce heat-resistant and corrosion-resistant surfaces. Utilized in research settings for doping in optical and electronic materials due to yttrium’s luminescent and conductive properties. Also serves in the development of specialty glasses and superconductors.
