PREPARATION OF CE0.8GD0.2O1.9 SOLID ELECTROLYTE BY THE SOL-COMBUSTION METHOD

Ce0.8Gd0.2O1.9 (GDC) powders were prepared by a novel sol-combustion method using citric acid as the chelating reagent. The effects of different sintering temperatures were investigated on the evolution of crystalline phase, particle size, and lattice parameters of the resulted GDC powders. The resu...
