Description
A fine pale yellow powder composed of particles of cerium oxide. As is the case for many nanomaterials, extensive research into applications of cerium oxide in nanotechnology continues, with early applications including fuel cells and glass manufacturing.

 

Applications


1-Coatings: Cerium oxide nanopowders play a role as an ingredient in several coatings, including heat-resistant coatings, rust-resistant coatings, UV-absorbing coatings, and IR filter coatings. CeO2 also plays a role in the use of superconductors, where it’s of value in coatings as a buffer layer.


2- Catalysts: Like many other nanomaterials, cerium oxide has been thoroughly researched and applied as a catalyst and catalyst support. It’s also of value as an additive for sintering and other metallurgical activities.


3- Fuel cells: Like many related nanomaterials, cerium oxide nanoparticles have been a key subject for research of fuel cells, with the ingredient being of particular use in the production of electrolyte and electrode materials in solid oxide designs.


4- Coloring agent: Cerium oxide has been used as a coloring for certain materials, including plastics, due to its unique optical agents at such diameters.


5-Oxygen devices: The unique traits of cerium oxide make it of particular use in certain devices dealing with oxygen, such as pumps and sensors.


6-Polishing: As a nanopowder, cerium oxide works particularly well as a polishing medium for ball bearings, various electronic devices, glass, and other devices and materials.


7-UV absorption: Few materials offer the same level of ultraviolet absorption per surface area available with cerium oxide, making it of particular interest in any number of coatings and shielding and an additive or base material. At 400nm, it absorbs more than any other oxide.
