Method for preparing cerium carbonate and cerium oxide |
摘要 |
Disclosed is a method for preparing cerium carbonate that can improve yield or productivity of cerium carbonate and enables preparation of cerium carbonate having uniform diameter, cerium carbonate, and a method for preparing cerium oxide. The method for preparing cerium carbonate comprises mixing the cerium precursor with urea; and, elevating the temperature of the mixture to 50° C. or more in the absence of a separate reaction medium to react the cerium precursor with urea in the presence of a polymer dispersant. |
