Synthesis and characterization of nanocrystalline La2Mo2O9 fast oxide-ion conductor by an in-situ polymerization method
چکیده انگلیسی

A nanocrystalline La2Mo2O9 powder was synthesized via the pyrolysis of polyacrylate salt precursor prepared by an in situ polymerization of the metal salts and acrylic acid. The pyrolysis behavior of the polymeric precursor was studied by thermal (TG/DTA) analysis. The obtained product was characterized by X-ray diffraction (XRD) and transmission electron microscope (TEM) analysis. The results revealed that the average particle size is ∼25 nm for La2Mo2O9 with good crystallinity. The synthesized nanocrystalline La2Mo2O9 powder showed good sinterability and reached ∼99% of theoretical density when sintered at 800 °C for 4 h. The La2Mo2O9 sample sintered at 800 °C, yield good microstructure with improved conductivity value of about 0.12 S/cm at 800 °C.
