Cerium Metal

• 

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: α´cerium occurs in C-centered orthorhombic at a pressure of 5.8 GPa and 25 °C; α cerium occurs in face centered cubic at atmospheric pressure and -196 °C; β cerium occurs in double hexagonal close packed at atmospheric pressure and 25°C; γ cerium occurs in face centered cubic at atmospheric pressure and 25 °C;and δ cerium is body centered cubic at atmospheric pressure and 768 °C. Cerium has a specific gravity of 6.771 g/cm3, a melting point of 798 °C, and a boiling point of 3433 °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 2210 °C, and a formula weight of 172.12. 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. Purity of our cerium metal:Ce/TREM = 99.5% - 99.9999% min Packing: In iron drums with inner double PVC bags of 100kg net each, or packed according to customers' specifications.
