Cerium dioxide from ceric ammonium nitrate


I just thermally decomposed ceric ammonium nitrate. I heated it at 200 C. then raised the temperature to 250-280 degrees and calcine it for another 2 hours.

How reactive is this CeO2? Can it be dissolved in acids? I have some CeO2, and that material is extremely inert and cannot be dissolved in concentrated acids, not even by boiling the acid. So, I am wondering how reactive your product is. I would like to have some CeO2, which is sufficiently reactive that it can be used to make other Ce-salts.

Why did you make useless CeO2 from usefull ammonium cerium(IV) nitrate?

Woelen: https://www.sciencemadness.org/whisper/viewthread.php?tid=15...

I read that molten bisulfate should also dissolve CeO2.




If you are interested in aqueous inorganic chemistry look at https://colourchem.wordpress.com/main-page/

I can offer GC analysis of samples. Just U2U to me for more info.

woelen i don't know to tell you truth. When i try i will write here.

Bedlasky i know how useful it is, but have a lot and i also want other cerium compounds for example tetravalent sulfate. Exept that i love when i have new reagent.
