| 中文摘要 | the precursor powder of ce0.9sm0.1o2-delta (sdc) containing 5.0x10(-4) (omega) sio2 as an impurity (sdcsi) was prepared by the sol-gel method and 0-3.0% (molar fraction, x) mgo was added to the sdcsi powder. the characterizations focused on phase structure, sintering behavior, relative density, electrical conductivity of all the samples were investigated by x-ray diffraction (xrd), field emission scanning electron microscopy (fe-sem), and ac impedance spectroscopy. we find that mgo can reduce the sintering temperature about 100-200. and increase the relative density of the ceramics. the grain boundary conduction increased markedly for the 1.0%(x) mgo-loaded sdcsi ceramics as mgo can mitigate the harmful effects of the sio2 impurity. these investigations have indicated that mgo is shown to be an effective sintering aid and a new scavenger of the grain boundary synchronously. |
