Abstract

Ce0.9Gd0.1O1.95nano-powders were synthesized by sol-gel method,glycine-nitrate process and carbonate co-precipitation method,respectively.The characterizations of the samples have been completed by XRD,TG-DTA and FT-IR.The influences of the synthesize methods and the sintering temperature on the size of the nano-powders were investigated.The results showed that the sintering temperature had a significant effect to the particle size of the powders.The minimum particle size was obtained when the sample was synthesized by the carbonate co-precipitation method and sintered at 500℃ for 2 h.
