Preparation and Characterization of LaMoO₃, La_xSr_yV_zO₃and La_xSr_yMo_zO₃Perovskite Type Oxides by the Sol-Gel Citrate Method

Abstract

In this study, LaMoO3, LaxSryVzO3 and LaxSryMozO3 perovskites have been prepared by the solgel citrate method and calcined at 1000• C for 5 h. Ammonium carbonate and citric acid were used as complexing agent and solvent. Phases of synthesized materials were characterized with X-ray diraction. Morphological analysis and elemental composition of perovskites were determined by scanning electron microscope and energy dispersive spectroscopy. The surface analyses of the solids have been studied using the BrunauerEmmettTeller surface analyzer. The eects of substitution of x, y, and z on the physical properties of the synthesized perovskites were also investigated.

Physical properties of Nano Crystalline Ceramic HoBaCrO

“…To prepare these materials, a wide variety of chemical techniques has been developed such as solid-state reaction method [23], co-precipitation [24], hydro-thermal [25], the Pechini [26] and sol-gel progress [27]. In this paper, perovskite-type oxide Ho 1-x Ba x CrO 3 was synthesized by sol-gel technique which is the simplest, most economical and less energy consuming route for nanoparticles synthesis.…”
