Sol–gel preparation and characterization of perovskite lanthanum lithium titanate

Lanthanum lithium titanate, belonging to the solid solution La0.66Li0.33TiO3, was prepared by sol–gel method from LiNO3, La(NO3)3 6H2O and Ti(OC4H9)4 in ideal cation stoichiometry for La0.66- Li0.33TiO3. The synthesized product was characterized by X-ray powder diffractometry (XRD) and thermal analyses (DTA-TG). Electron microscopy investigations (SEM and TEM) was used to evaluate the morphology of synthesized La0.66Li0.33TiO3. The bulk quantities of nano-sized particles of layered La0.66Li0.33TiO3 have been obtained at 1,000 C using the modified sol–gel method. The mean diameter of La0.66Li0.33TiO3 nano-crystals was about 123 nm.
