Cerium Oxide CeO2 powder CAS 1306-38-3

About Cerium Oxide CeO2 powder:
Cerium(IV) oxide, also known as ceric oxide, ceric dioxide, ceria, cerium oxide or cerium dioxide, is an oxide of the rare-earth metal cerium. It is a pale yellow-white powder with the chemical formula CeO2. It is an important commercial product and an intermediate in the purification of the element from the ores. The distinctive property of this material is its reversible conversion to a non-stoichiometric oxide.
Cerium oxide has a density of 7.13g/cm3 and a melting point of 2397℃. It is insoluble in water and alkali, but slightly soluble in acid. Under the temperature of 2000 ℃ and 15 mph pressure, can be achieved by hydrogen reduction cerium oxide, cerium oxide, temperature between 2000 ℃ and free pressure-free in 5 mph, cerium oxide is light yellow, reddish and pink, its performance is to be polished material, catalyst, catalyst carrier, (assistant), UV absorber, fuel cell electrolyte, automobile tail gas absorber, electronic ceramics, etc. Feel free to send an inquiry to get the latest price if you would like to buy Cerium Oxide CeO2 powder in bulk.

Performance of Cerium Oxide CeO2 powder:

At a temperature of 2000℃ and a pressure of 15MPa, cerium oxide can be reduced by hydrogen to obtain cerium oxide. When the temperature is free at 2000℃ and the pressure is free at 5MPa, the cerium oxide is yellowish and reddish, and pink. Its performance is to make polishing materials, catalysts, catalyst carriers (auxiliaries), ultraviolet absorbers, fuel cell electrolytes, automobile exhaust absorbers, electronic ceramics, etc.

How is Cerium Oxide CeO2 powder produced?
The production method of cerium oxide is mainly oxalic acid precipitation method, that is, using cerium chloride or cerium nitrate solution as raw material, using oxalic acid to adjust the pH value to 2, adding ammonia to precipitate cerium oxalate, after heating and curing, separation, washing, drying at 110℃, and then burning at 900 ~ 1000℃ to form cerium oxide
CeCl2 + H2C2O4 + 2 NH4OH and CeC2O4 + 2 H2O+ 2 NH4Cl
 
Applications of Cerium Oxide CeO2 powder:
Oxidant.
Organic reactive catalyst.
Steel analysis is a rare earth metal standard.
Oxidative Titration Analysis.
Decorative glass.
Glass enamel shielding agent.
Heating alloy.
It is used as a glass industrial additive, and the plate glass abrasive material can also be used to act as an ultraviolet ray in cosmetics.
It has been expanded to the glasses glass, optical lens, the abrasion of the image tube, from the absorption of ultraviolet rays and electronics of the glass.
The primary ingredients of the cerium oxide polishing powder are cerium oxide (CeO2), followed by cerium oxide (La2O3), oxide (PR2O3), magfuric lanthanide (LaOf), but also contain trace silicon oxide, alumina and calcium oxide . The polishing effect is affected by polishing powder is the particle size, purity and hardness of CeO2.
Since nano-CEO2 has a wealth of electronic transition capability, excellent optical sensitivity is absorbed to ultraviolet light. The small dimensional effect of nanoparticles, high-proportion surface effects, macroscopic quantum effects, strong scattering and reflection of ultraviolet light.

Storage Condition of Cerium Oxide CeO2 powder:
Cerium Oxide CeO2 powder should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition, should avoid the heavy pressure, according to ordinary goods transportation.
