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 non-stoichiometric 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 cerium oxygen, or cerium oxide can be used at temperatures of 2000 to 15 mph. It is also possible to achieve this temperature by using cerium oxide as a catalyst.

Cerium oxide CeO2 powder performance:
To make cerium oxide, hydrogen can reduce cerium oxide to a solution at 2000 degrees Celsius and 15 MPa. 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, catalysts (auxiliaries), fuel cell electrolytes as well as automobile exhaust absorbers, electronic ceramics and other applications.
