Erbium(III) nitrate pentahydrate - Production process
1. Heat erbium oxide to a high temperature and dissolve it in nitric acid, and then evaporate and concentrate to obtain its pentahydrate or hexahydrate salt.
2. Under heating, the excess erbium carbonate reacts with concentrated nitric acid, and after the reaction, the unreacted oxide is filtered and separated. Cooling the obtained nitrate solution to obtain erbium (III) carbonate pentahydrate.
3. Dissolve erbium carbonate in slightly excess 8mol/L nitric acid, evaporate and concentrate to paste, and recrystallize with dilute nitric acid for the second time. Then put it in a 50% ~ 60% sulfuric acid dryer for drying.
