Used as a precursor in the production of cerium-based catalysts and ceramics. Employed in the synthesis of luminescent materials and phosphors for lighting and display technologies. Applied in research for developing new functional materials due to its thermal decomposition properties. Also utilized in the preparation of high-purity cerium oxide by calcination, which is important in polishing powders for glass and semiconductors. Additionally, serves as a starting material for photocatalysts used in environmental applications, such as the decomposition of pollutants under sunlight.
