Cerium Oxide CeO2 powder:

Cerium(IV), commonly known as cericoxide, ceric dioxide, or cerium dioxide, is an oxide made from rare-earth metal, cerium. It’s a yellowish-white powder that has the chemical composition CeO2. is an important commercial product that also serves as an intermediate for the removal of elements from ores. Its reversible transformation to a nonstoichiometric ore is the distinctive characteristic of this material.

Ceriumoxide has a density 7.13g/cm3 at a melting point 2397. Cerium oxide is insoluble with water and alkali but can be slightly dissolved by acid. Hydrogen reduction ceriumoxide can be used to achieve cerium oxide at temperatures of 2000 and 15, mph. It is also soluble in alkali and water.

Cerium oxide CeO2 powder performance:

To make cerium oxide, hydrogen can reduce cerium oxide to a solution at 2000 degrees Celsius and 15MPa. The cerium oxide will turn yellowish or reddish if the temperature is at zero at 2000, but it is at no pressure at 5MPa. The cerium oxide is used in the manufacture of polishing and catalyst materials, catalyst carriers, (auxiliaries), catalysts, catalysts carrier, ultraviolet absorbers fuel cell electrolytes automobile exhaust absorbers, electronic ceramics etc.

Cerium Oxide CeO2 dust


Producing cerium oxide by oxalic acids precipitation is the most common method. That is, starting with cerium chloride/cerium nitrate as a raw material and using oxalic to adjust its pH to 2. Then adding ammonia and heating to precipitate cerium dioxide. Finally, burn it at 900 1000.

Cerium Oxide CeO2 dust applications


Cerium oxide glass polish


Organic reactive catalyst

The steel analysis is an indicator of rare earth metals.

Oxidative titration analysis.

Decorative glass

Glass enamel shielding agent.

Alloy heating.

Using cerium oxide

It can also be used in the manufacture of glass additives and as a plate glass abrasive.

It is now able to be expanded for the glass glass, optical lenses, and the abrasions of the tube.

It is made up of two primary components:

Polishing of cerium oxide

Cerium oxide is the most common powder, followed by Cerium dioxide (CeO2) and Cerium oxide [La2O3], cerium oxid (La2O3). Magnuric lanthanide, LaOf), magfuric oxide (LaOf), Cerium oxide (1PR2O3) are other options. But, they also have trace levels of calcium oxide, silicon oxide, and alumina. What determines the polishing effect of polishing powder? It is how small, pure and hard CeO2 is.

Because nano-CeO2 offers a wide range of electronic transformation capabilities, it is very sensitive to ultraviolet light. High-proportion surfaces effects, macro quantum effects, weak scattering, reflection, and small-dimensional effects of nanoparticles are all possible.

Cerium Oxide CeO2 powder storage condition:

Cerium Oxide CeO2 should be kept in a dry and clean environment. It should not be exposed to air.
