What are the main uses of Cerium(3+) trichloride (CAS: 7790-86-5)?

Cerium(3+) trichloride is primarily used in catalytic applications, such as petroleum refining and polymerization reactions. It serves as a colorant in glass and ceramics, enhancing transparency and refractive index. Additionally, it is employed in the production of other cerium-based materials and in research for its redox properties, though direct consumer or food applications are rare.
