| 摘要 |
The present invention relates to a method for preparing cerium carbonate-based compound, which is capable of easily controlling the crystalline structure, size, shape, or etc. of the cerium carbonate-based compound, and of preparing the cerium carbonate-based compound efficiently at low cost. The method for preparing cerium carbonate-based compound includes comprising the steps of reacting Lanthanite-(Ce) at an elevated temperature to form cerium oxycabonate hydrate (Ce 2 O(CO 3 ) 2 · H 2 O) with orthorhombic crystal structure, or cerium hydroxycarbonate (Ce(OH) · (CO 3 )) with hexagonal crystal structure. |
