Used as a source material in research and development for rare earth applications, particularly in metallurgy and alloy production. Commonly employed in physical vapor deposition and thermal evaporation processes due to its high purity and ease of handling when stored in paraffin oil. Serves as a precursor for synthesizing cerium-based compounds in catalysis, such as automotive catalytic converters and industrial oxidation catalysts. Also utilized in the fabrication of specialized optical coatings and semiconductor materials. Its thickness makes it suitable for machining into custom components for laboratory-scale experiments involving neutron absorption or radiation shielding studies.
