説明
Synthesis of the Ce0.9Gd0.1O1.95(CGO) powder by polymeric precursor solution with mixing of nitrates, nitric acid and ethylene glycol was investigated with emphasis on the effect of polymerization of the precursor solution on the crystallization and morphology of the derived solid intermediate and the final oxide powder. It is first evidenced that the solid intermediate derived from the polymerized solution exists in the form of well-crystallized cerium-gadolinium formate solid solution, Ce1-xGdx(HCOO)3, exhibiting the polycrystalline and anisotropic growth morphology. Moreover, the intensive polymerization of the precursor solution results in the direct formation of the loosely agglomerated nano-scaled CGO oxide powder at the temperature as low as 130°C. The effects of nitric acid and nitrates on the polymerization of the precursor solution are identified experimentally, based on which, a polymerization mechanism of the ethylene glycol process is proposed.
