Comparison of Nanocrystalline LaMO3 (M = Co, Al) Perovskite Oxide Prepared by Co-Precipitation Method

Wankassama Haron, Anurat Wisitsoraat, and Sumpun Wongnawa
Abstract—Nanostructured perovskites with formula LaMO3 (M = Co, Al) were synthesized by the co-precipitation method and characterized with X-ray Diffraction (XRD), Energy Dispersive X-ray Spectrometry (EDX), X-ray Fluorescence spectrometry (XRF) and Scanning Electron Microscopy (SEM) techniques. The XRD pattern confirmed that all samples are perovskite oxide. Elemental compositions of LaMO3 were investigated by EDX. The EDX pattern of LaCoO3 showed the presence of La, Co, and O while La, Al, O and K (as impurity) were detected in LaAlO3. SEM micrographs indicated that all perovskite samples were nanosized particles having difference morphologies.

Index Terms—Perovskite, LaCoO3, LaAlO3 , co-precipitation method.
