Effects of Doped AE (Ca, Sr) on Synthesis and Structure of Lanthanum Chromite-Based Nano-Powder

Abstract:

Using sol-gel method, a series of nanocrystalline materials La_1-xAE_xCrO₃ (AE=Ca, Sr) were synthesized. Difference between Ca- and Sr-doped lanthanum chromites were investigated by carrying out differential scanning calorimetry (DSC), thermogravimetric analysis (TG), X-ray diffraction (XRD) and high resolution transmission electron microscope (HRTEM). It was found that the synthesis temperature (1-xCa_xCrO₃, and CaCrO₄ as the second phase (x≥0.2) at the room temperature. LSC is composed of single orthorhombic perovskite phase for x=0.1, while the orthorhombic and rhombohedral perovskite phases coexist for x=0.2, and only rhombohedral perovskite phase for x=0.3. Further studies showed that the maximum solubility of Sr was lower than that of Ca in lanthanum chromite.
