Nanometer cerium dioxide particles were synthesized by using advanced microwave synthesis technology,the materials included Ce(SO_4)_2·4H_2O and NaOH,the surfactant was polyglycol(PEG) which could disperse and protect the products.The effect factors in the process of preparing nanometer cerium dioxide by microwave were explored individually,and the orthogonal method was adopted to confirm the optimum process condition.The optimum process conditions include the reaction volume of PEG is 9 mL,the washing volu...
