Method for the production of mixed ammonium-rare earth oxalates and their application to the production of rare earth oxides |
| abstract |
The present invention relates to a process for manufacturing a double ammonium and rare earth oxalate comprising mixing, in an aqueous medium, compounds capable of releasing oxalate ions with a soluble rare earth salt and an ammonium salt such than ammonium nitrate.n n n The precipitate is then separated and washed.n n n The double oxalate obtained is transformed into yttrium oxide by calcination. |
