Glycine-nitrates combustion synthesis and properties of nano-sized Ce_1-xGd_xO_2-_d solid solution for solid oxide fuel cell viewpoint

Abstract

Nanocrystalline gadolinium-doped ceria powders for solid electrolytes have been successfully prepared via glycine nitrate combustion synthesis and characterized by TGA/DTA, XRD and SEM. Using these powders; highly dense ceramics have been prepared by sintering at 1100°C which is much lower temperature than 1600°Cusually required for ceria solid electrolytes prepared by conventional ceramic technique. The effect of compositions on structure and conductivity has also been studied.
