What is a Cerium chloride (CeCl₃)?

Cerium chloride (CeCl₃) is an inorganic compound composed of cerium (Ce) and chlorine (Cl) with the chemical formula CeCl₃. Cerium is a rare earth element and a member of the lanthanide series, known for its relatively high reactivity. Cerium chloride typically forms colorless or pale yellow crystals and is highly soluble in water. This compound is utilized in various applications, taking advantage of cerium's chemical properties. Cerium chloride is primarily used in catalysis and chemical reactions. It can serve as a catalyst in redox reactions, especially in organic chemistry, such as oxidation and hydrogenation processes. Additionally, cerium chloride is used alongside cerium oxide in industrial applications, particularly in gas sensors and as a catalyst in chemical reactions.

Cerium chloride is relatively inexpensive and is utilized in optical materials and fluorescent compounds. Cerium-containing compounds are known for their fluorescence, making cerium chloride useful in specific optical applications. In terms of environmental impact, cerium chloride is considered stable and manageable under proper conditions, with limited risk of danger when handled appropriately.
