中文摘要In thiswork,well-dispersed nanopowder of Ce0.9Gd0.1O1.95 (gadolinia doped ceria, GDC)was synthesized by a novel sol−gel thermolysis method using a combination of citrate acid and polyvinylpyrrolidone (PVP). PVP performed as a surfactant and its amountwas optimized in terms of GDC powder morphology. The physical and chemical properties of the resultants were characterized by XRD, TG/DTA, FT–IR, SEM, BET and PSA. From the XRD patterns, well-crystalline cubic fluorite structured GDC was obtained after calcining the precursor at 600 ℃. The SEM observation showed an average particle size of about 15nm for the optimal GDC powder and particle size analysis (PSA) gave a narrow distribution of particle size. The sintering experiment showed a good sinterability and a relative density of 94% was achieved at 1300℃. The dense sample exhibited an ionic conductivity of 0.017 S cm−1 at 600 ℃ in air.
