Description
An improved method is proposed for the preparation of lanthanum manganite (LaMnO3) powder by the calcinations of a composite carbonate of the respective metallic elements formed by mixing an aqueous solution of a water-soluble ammonium carbonate and an aqueous solution of inorganic salts, e.g, chloride, of the respective metallic elements. The surface morphology of the LaMnO3 has been studied by scanning electron microscopy (SEM) and the wavelengths of the fluorescent X-rays (XRF) can be measured by an X-ray spectrometer as means of chemical analysis. Structural properties is characterized by XRD. Chemical and physical reaction of LaMnO3 powder is investigated by TGA-DTA. The perovskite-structured La1-x MnxO3 (x=0.01, x=0.99) can accommodate at the A-site deficiency.
