The present invention to relates to a cerium oxide production method in the method for producing a novel hydroxide, cerium carbonate, and the nanocrystals size using the same mixing and more particularly, cerium salt, hydroxide and carbonate solution to prepare a hydroxide, cerium carbonate, by using this relates to a process for producing cerium oxide of the nanocrystal size, by developing a new method to obtain the hydroxide of cerium carbonate in a high yield even at a low temperature and a short aging time when cerium oxide of the nanocrystal size, conventional oxidation cerium to shorten a long aging time and high temperature conditions involved in the manufacture, as well as the simplification of the simplicity and facility of process be hydroxide, cerium carbonate in high yield and economically to to lower the manufacturing costs increase the productivity suitable for mass production It relates to a method for preparing cerium carbonate hydroxide and a method for preparing cerium oxide using the same size of the nanocrystals to produce a cerium oxide with a high quality of the nanocrystal size.
