The structure and thermal properties of Ba 0. 5 La 0. 5 MnO3 polycrystalline powder have been investigated using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) techniques. The structural studies have shown that Ba 0. 5 La 0. 5 MnO3 compound crystallizes in perovskite structure with Pm-3m cubic symmetry group. The lattice parameters were obtained to be a = b = c = 3.9073 Å. Mass changes have been observed from thermogravimetric (TG) and differential thermogravimetric (DTG) curves obtained in a wide temperature interval of 30–950 ∘ C. Free energy and enthalpy changes for all observed transformations were determined. Observed endo and exo effects. [ABSTRACT FROM AUTHOR] |
