Caesius Posted November 15, 2012 Share Posted November 15, 2012 One method that i found was by electrochemical reduction. Is there any other ways? If you could find a more active metal than cerium (if I could make a guess, aluminum or magnesium), you might be able to come up with a thermite-like reaction reducing the cerium. CeOx(s) + Al(s) => Ce(l) + Al2O3 (unbalanced) OR CeOx(s) + Mg(s) => Ce(l) + MgO (unbalanced) My best guess is that magnesium is more likely to work because it is a slightly stronger reducer than aluminum. You will have to do some research and see whether or not magnesium and aluminum are stronger reducers than cerium, I couldn't find out right away. If they are, then I believe this may work a little like a thermite reaction. Link to comment Share on other sites More sharing options...

chilled_fluorine Posted November 17, 2012 Share Posted November 17, 2012 Have any sodium metal? Otherwise, just do the same for (almost) anything: mix it with magnesium and light it on fire. Link to comment Share on other sites More sharing options...

Magnesium is not reactive enough for cerium; I tried this with stochiometric quantities, and all I got was an odd green powder (this was white ceria, very pure, too. Not mine, though). Unfortunately, I did not have access to argon at the time, so it could be that all the cerium produced immediately burned away. I would suggest lithium, or as you said, sodium. Potassium is overkill... but worth a shot if the others fail. Link to comment Share on other sites More sharing options...
