Preparation and Characterization of Gd1-xSrxCoO3-δ
GdSrCoO3-δ and Gd1-XSrXCoO3-δ (x=0.1~0.5) were synthesized using glycine-nitrate process (GNP). The formation process of perovskite phase and microstructure of powders were characterized using TG-DTA and XRD. All the powders with different doping amounts of Sr2+ on A-site were single-phase solid solutions, and the stable perovskite phase was formed completely after calcination at 1100°C. The crystal structures of the solid solutions transfer to a higher symmetrical perovskite.
