摘要

The phase transition and growth of yttria-stabilized zirconia (YSZ) nanocrystallites prepared by a sol-gel process with various amounts of ZrOCl ₂ ·8H ₂ O and Y(NO ₃ ) ₃ ·6H ₂ O in ethanol-water solutions at low temperatures were studied. DTA/TGA, XRD, and TEM were used to characterize the YSZ nanocrystallites. The crystallization temperature of 3YSZ, in which Y ₂ O ₃ /(Y ₂ O ₃ +ZrO ₂ ) = 0.03 gel powders, estimated by DTA/TG is about 427°C. When 3YSZ and 5YSZ gels were calcined at 500°C, their crystal structures were composed of coexisting tetragonal and monoclinic ZrO ₂ . Cubic ZrO ₂ was obtained when added Y ₂ O ₃ was greater than 8 mol%. A nanocrystallite size distribution between 10 and 20 nm was obtained from TEM observations.
