英文摘要	Fe and Mn-doped Ce0.83Sm0.085Nd0.085O2-&(SNDC) powders are successfully synthesized by the simple and efficient solid-liquid method. The crystallinity and morphologies of the powders were characterized by X-ray diffractometer, Raman spectrum, and scanning electron microscopy. The effect of doping on sintering behavior, grain interior, and grain boundary conductivity are studied. The doping of Fe can effectively reduce the sintering temperature from 1450(o)C to 1250 degrees C and keep the same density. Compared with SNDC, 1 mol% Fe-doped SNDC (Fe-SNDC) sintered at 1250 degrees C shows a higher total conductivity of 2.13 x 10(-2)S center dot cm(-1)at 650 degrees C. Also, it exhibits that doping of Fe can increase the conductivity of grain interior and grain boundary simultaneously. The present work shows that the Fe-SNDC synthesized by solid-liquid method can be used as a potential electrolyte for intermediate-temperature solid oxide fuel cells.
