  The synthesis of nano crystalline particles of cerium oxide at room temperature was investigated in detail. Highly crystallized cerium oxide nano powder with a particle size of 10 nm was obtained by adding a hydrazine aqueous solution or an ammonia aqueous solution into a cerium nitrate solution followed by stirring the mixed solutions over a prolonged period at room temperature. It was considered that the good crystallinity was attributable to the use of an aqueous solution containing Ce(III) ions as a starting solution.
