METHOD FOR PREPARING CERIUM CARBONATE AND METHOD FOR PREPARING CERIUM OXIDE POWDER

摘要

The present invention relates to a method for preparing cerium carbonate which can improve the yield and productivity of cerium carbonate, to cerium carbonate powder, and to a method for preparing cerium oxide powder using the same. The method for preparing cerium carbonate comprises the steps of: mixing cerium precursors and urea; and reacting the cerium precursors and urea by raising the temperature of the mixture to 50-250? in a solvent-free state.
