Used as a precursor in the synthesis of cerium oxide (CeO₂) nanoparticles, which are widely applied in catalytic converters to reduce automotive emissions. It serves as a dopant or starting material in the production of phosphors for fluorescent lamps and display technologies. Employed in the preparation of coatings for glass and mirrors due to its high refractive index and UV absorption properties. Applied in research and development of solid oxide fuel cells (SOFCs) as a component in electrolyte materials. Utilized in the textile and leather industries as a mordant to improve dye adhesion. Also used in the formulation of catalysts for organic reactions, including oxidation processes in chemical manufacturing.
