Cerium (Ce) Sheet

Product Code : RE-Ce-5N-SP

Cerium, like all lanthanides, is slightly toxic. Metallic cerium can ignite from 65 ° C. As a finely divided metal, it can heat up in the air without energy and finally ignite. Among other things, the ignition readiness depends very much on the particle size and the degree of distribution. Cerial fires must not be extinguished with water as gaseous hydrogen evolves.

Cerium Metal is available as disc, granules, ingot, pellets, pieces, powder, rod, sputtering target, wire, and in numerous other forms and custom shapes.  Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, quantum dots, targets for thin film deposition, pellets for evaporation and single crystal or polycrystalline forms. Elements can also be introduced into alloys or other systems as fluorides, oxides or chlorides or as solutions. Cerium metal is generally immediately available in most volumes.

Features

1. The silvery white shiny metal is the second most reactive element of the lanthanoids after europium. Superficial damage to the protective yellow oxide layer ignites the metal. Above 150 ° C it burns with a violent glow to form ceria. It reacts with water to form cerium hydroxide.

2. Cerium occurs in compounds as a trivalent colorless or tetravalent yellow to orange cation.

3. Under the influence of heat, it is strongly attacked by ethanol and water. It is also heavily attacked in alkalis to form cerium hydroxides. In acids, it is dissolved into salts.
4. Since the chemical properties of rare earths are similar, metallic cerium is rarely used in pure form, but in the mixture in which it is obtained in the production of the rare earth minerals, the so-called mischmetal.


Cerium (Ce) Metal Application

Cerium compounds have a number of practical applications. Cerium, together with the other rare earth elements, is part of many iron alloys to trap sulfur and oxygen and to crosslink cast iron. It is also used in non-ferrous alloys, especially for improving the high-temperature oxidation resistance of superalloys. Mischmetal (typically 50 percent cerium, 25 percent lanthanum, 18 percent neodymium, 5 percent praseodymium and 2 percent other rare earths) is mainly used for lighter flintstones and alloying additions.

In metallurgy, cerium is used as an additive for aluminum alloys and high-temperature-resistant iron-based alloys. It supports the separation of sulfur and oxygen in the melting process. The iron-mischmetal alloy Cereisen serves as the starting material for flints for use in lighters and for generating sparks on roller coasters and in movie scenes (accident scenes). 

Cerium(Ill) oxide has uses as a catalyst. It is used in the inside walls of self-cleaning ovens to prevent the build-up of cooking residues. It is also used in catalytic converters. Cerium(III) oxide nanoparticles are being studied as an additive for diesel fuel to help it burn more completely and reduce exhaust emissions.

Cerium sulfide is a non-toxic compound that is a rich red colour. It is used as a pigment.

Cerium is also used in flat-screen TVs, low-energy light bulbs and floodlights.


Small additions of (more or less pure) cerium compounds impart certain properties to other materials:

1. Ceria (CeO 2) is used to stabilize the alumina ceramic catalyst support for automotive exhaust catalysts.

2. Part of some special lenses, for example UV filters and windshields, and dehumidifiers in glass manufacturing

3. For coloring enamel

4. Ceria is used as a polishing agent in glass processing

5. Cerium-doped fluorescent dyes (phosphors) in picture tubes and white LEDs

6. As doping in mantles

7. Self-cleaning ovens contain a cerium-containing coating

8. Cerium (IV) sulfate as oxidizing agent in Quantitative Analysis (Cerimetry)

9. As a contrast agent at nuclear resonance

10. As a phosphor in gas discharge tubes

11. Added to the regeneration of soot particle filters dissolved in the fuel

12. As part of non-precious metal-containing bonding alloys in dental technology (ceramics)

13. As an oxidant for organic syntheses with CAN (cerium ammonium nitrate), (NH4) ²Ce (NO³) 6
