摘要
采用改进的Pechini法制备了Sm2Ti2O7和sm2ti1.8 ce0.2 2o7样品。利用x射线衍射(XRD)、拉曼光谱(Raman spectroscopy)和扫描电镜(scanning electron microscopy)对高还原气氛下结构和形貌的演变进行了表征。铈似乎促进了二氧化钛的还原，导致正构SmTiO3的形成。
Influence of cerium dopant on pyrochlore structure evolution under highly reducing atmosphere
Sm2Ti2O7 and Sm2Ti1.8Ce0.2O7 samples have been synthesized using a modified Pechini method. The evolution of structure and morphology under highly reducing atmosphere was evidenced using X-ray diffraction (XRD), Raman spectroscopy and scanning electron microscopy. Ceria seems to facilitate the reduction of titania, leading to the formation of orthorombic SmTiO3.
