Used in the production of yttrium oxide, which is essential for making red phosphors in cathode ray tubes and LED displays. Employed in ceramics and glass manufacturing to enhance thermal stability and resistance to cracking. Serves as a precursor in the synthesis of yttrium-based catalysts for industrial chemical reactions. Applied in the development of specialty coatings for aerospace components due to its high-temperature performance. Also utilized in research for solid oxide fuel cells as a component in electrolyte materials.
