Cerium (Ce)

Cerium is a lustrous silvery-dark grey metal that oxidizes readily in air. Finely divided cerium metal is very unstable in air. The metal is malleable and will likely ignite if cut with a knife. The element has three valence states, *2, *3, and *4, with the *2 state being rare. Cerium metal has five allotropes and four metal crystal forms: αcerium occurs in C-centered orthorhombic at a pressure of 5.8 GPa and *5 °C; α cerium occurs in face centered cubic at atmospheric pressure and ***6 °C; β cerium occurs in double hexagonal close packed at atmospheric pressure and *5°C; γ cerium occurs in face centered cubic at atmospheric pressure and *5 °C;and δ cerium is body centered cubic at atmospheric pressure and **8 °C. Cerium has a specific gravity of 6.**1 g/cm3, a melting point of **8 °C, and a boiling point of ***3 °C. Cerium oxide, or ceria, occurs as the dioxide, its most stable form, with the formula CeO2. It also occurs as the sesquioxide with the formula, Ce2O3. The oxide is a white powder with a specific gravity of 7.3gm/cm3, a melting point of ***0 °C, and a formula weight of **2.*2.

Cerium oxide is widely used to polish glass surfaces.  Other Cerium compounds are used to manufacture glass and enamels both as ingredients, as well as colour removal agents. Cerium is a component in solar panels, LEDs, catalytic converters, thermal resistance alloys, carbon arc lighting, self-cleanin govens, petroleum refining, hardening agents, and dental ceramics.
