Used as a precursor in the synthesis of cerium oxide nanoparticles, which are applied in catalytic converters for automotive emission control and solid oxide fuel cells (SOFC).

Serves as a dopant or oxidizing agent in glass and ceramic manufacturing, enhancing UV absorption, providing decolorizing properties, and used in special optics like lenses requiring specific light absorption.

Employed in corrosion-resistant coatings and primers for aluminum and its alloys due to its inhibitive properties, forming highly effective protective films.

Utilized in the production of phosphors for lighting and display technologies.

Applied in water purification and wastewater treatment for absorbing and precipitating contaminants, particularly phosphates and certain organic compounds.

Also finds use in laboratory settings as a reagent for analytical chemistry and materials research, serving as a source of cerium for new compound synthesis.
