摘要
用Ｓｍ ２Ｏ３和Ｇｄ２Ｏ３共同掺杂ＣｅＯ２基电解质组分（ＣｅＯ２）０９（Ｓｍ ２Ｏ３）００５（Ｇｄ２Ｏ３）００５随着烧结温度的提高，晶粒持续长大，由１４００℃烧结时的２～３μｍ 长大到１６００℃烧结时的１０～１２μｍ ，单位尺寸内的晶界数量减少；各温度烧结样品的断口都呈穿晶断裂。ＣｅＯ２基电解质可以在１４００～１４５０℃烧结并获得较高电导率：８００℃时约为７Ｓｍ － １．随着烧结温度的提高，电导率下降，这可能是由于晶间玻璃相的增多造成的。
The grain size of Ceria based electrolyte complex stabilized with Sm 2O 3 and Gd 2O 3 increases continuously from 2～3 μm to 10～12μm with the raise of sintering temperature from 1400℃ to 1600℃.The number of granular interface in unit area decreases,too.The intercrystalline fracteru for samples sintered at different temperature is all obseared.Ceria based electrolyte can be sintered at 1400～1450℃ and its electrical conductivity is as high as 7 S.m -1 at 800℃.The electrical conductivity decreases with the increasing of sintering temperature.It may be ascribed to the increasing of intergranular glass phase.
