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 ynthesized La0.66Li0.33TiO3. The bulk quantities

Nanometer-sized perovskite - type oxides LaCo0.4Fe0.6O3 particles were synthesized by the modified sol-gel method, from La(NO3)3, Fe(NO3)39H2O and Co(NO3)26H2O an ideal cation stoichiometry for LaCo0.4Fe0.6O3 perovskite. Ethylenediaminetetraacetic acid (EDTA) was used like chelating agent. A light brown homogeneously mixed gel was prepared and transferred into a porous resin intermediate through charring. The precursors and derived oxide powders
