Hydrothermal Synthesis and Characterization of Oxygen Deficient Compounds La2/3TiO3-λ (λ=0.000~0.046) Powders

Abstract

Abstract: The series deficient compounds La_2/3TiO_3-λ(λ=0.000-0.046) powders were hydrothermallysynthesised from double hydrous oxides La₂O₃·3TiO₂·nH2O, and characterized by XRD, TEMand other technologies. The cell volumes of the products would change to large with the increasingof deficient oxidation, and the crystal symmetry transforms from orthorhombic to tetragonal at λ=0.020. The payticle-sizes of these powders were about 0.1~0.3μm with a mode of particle-sizedistribution, and increased with the increasing of deficient oxidation.

Key words: deficient compound, La2/3TiO3-λ, hydrothermal sythesis
