Preparation of GDC Nanopowders and GDC/YSZ Core-Shell Nanocomposites

摘要

Nanocrystalline GDC as small as 5 nm was successfully synthesized via the co-precipitation method.GDC/YSZ core-shell nanocrystals,which were GDC nanocrystals overcoated by a thin YSZ layer,was successfully synthesized by the addition of GDC nanocrystals in the YSZ source solution using sol-gel method.The core-shell structure was supported by its high-resolution transmission electron microscopy results and the composition was investigated by EDX method.
