METHOD FOR PREPARING CERIUM CARBONATE

摘要

The present invention relates to a method for preparing cerium carbonate which enables preparation of hexagonal cerium carbonate by a simplified process, a cerium carbonate powder prepared thereby, and a method for preparing a cerium oxide powder using the same. The method for preparing cerium carbonate comprises the step of contact-reacting orthorhombic cerium carbonate with a primary alcohol aqueous solution comprising water and primary alcohol at a weight ratio of 1:0.1 or more at a temperature of 160 °C or more to form hexagonal cerium carbonate.
