CRYSTALLINE CERIUM OXIDE AND METHOD FOR PREPARING SAME

摘要

The present invention relates to a crystalline cerium oxide which has an easily adjustable crystal structure, shape and size, and superior abrasive characteristics, and which can be prepared in an economically advantageous and efficient manner through a simple process, as well as to a method for preparing the crystalline cerium oxide. The crystalline cerium oxide can be a submicron crystalline cerium oxide having a volume mean particle diameter of a predetermined range and standard deviation of particle diameters of a predetermined range.
